The solution of the system of equations is (x, y) = (9/2, -7/10).

What is the system of linear equations?

A system of linear equations is a group of one or more linear equations that can be solved by using a simultaneous equation or elimination method. Therefore, by using the substitution method and writing the solution of the system in terms of coordinate point (x, y) = (-1, 1).

To solve a system of equations, we can use any of the following methods:
Substitution method,
Elimination method,
Matrix method.
Let's use the substitution method to solve the given system of equations.
We can solve the first equation for z:
z = 7 - 3x - 2y
Substituting this expression into the third equation, we get:
3x + 2y + 3(7 - 3x - 2y) = 1
This simplifies to:
-5x - 3y + 21 = 1
Adding 5x and 3y to both sides, we get:
21 = 5x + 3y + 1
Subtracting 1 from both sides, we get:
20 = 5x + 3y
Dividing both sides by 5, we get:
4 = x + 3/5 y
Substituting this expression into the first equation, we get:
3(x + 3/5 y) + 2y + 7 = 7
This simplifies to:
2y = -7/5
Dividing both sides by 2, we get:
y = -7/10
Substituting this value into the expression for x, we get:
x = 4 - 3/5(-7/10)
This simplifies to:
x = 4 + 21/10
x = 9/2

Hence, the solution of the system of equations is (x, y) = (9/2, -7/10).

Step-by-step explanation:

The value of x which will make the equation 8 + x = 32 true will be 24 thus, option (B) is correct.

There are many different ways to define an equation. The definition of an equation in algebra is a mathematical statement that demonstrates the equality of 2 mathematical expressions.

The equation must be constrained with some constraints.

As per the given equation,

8 + x = 32

Put x = 4

8 + 4 = 12 ≠ 32

Put x = 24

24 + 4 = 32 (so it will be the solution)

Hence "The value of x which will make the equation 8 + x = 32 true will be 24".

we find the restrictions after finding the reciprocal

A division is a process of splitting a specific amount into equal parts.

The values that give a value of 0 in the denominator are the restrictions.

To divide rational expressions, multiply by the reciprocal of the divisor.

The restrictions to the domain of a product consist of the restrictions to the domain of each factor.

To solve this we changes to reciprocal

The reciprocal rule of division method is “Multiply the dividend by the reciprocal of the divisor”.

Hence, we find the restrictions after finding the reciprocal

The definition of an equation in algebra is a mathematical statement that demonstrates the equality of two mathematical expressions. For instance, the equation 3x + 5 = 14 consists of the two expressions 3x + 5 and 14, which are separated by the 'equal' sign.

Remove parentheses from each side of the equation and combine similar terms to make it simpler.

To separate the variable term on one side of the equation, use addition or subtraction.

To find the variable, use division or multiplication.

Using mathematical operations, we know that the total number of workers in the company is 3,800.

A mathematical "operation" is the process of calculating a value utilizing operands and a math operator.

There are predefined rules associated with the math operator's symbol that must be applied to the supplied operands or numbers.

Parentheses, Exponents, Multiplication, Division, and Addition Subtraction are also known as PEMDAS (from left to right).

So, we know that 80% of all workers are women.

760 people who work for the company are not women.

Which means:
80% = x

20% = 760

Now, calculate the total workers as follows:

80/x = 20/760

20x = 80 * 760

x = 80 * 760/20

x = 3,040 (Women workers)

Total workers: 3040 + 760 = 3,800 workers

Therefore, using mathematical operations, we know that the total number of workers in the company is 3,800.

The slope of the graph of the line is 40.

The slope of a line is the ratio of the amount that y increases as x increases some amount. Slope tells you how steep a line is, or how much y increases as x increases. The slope is constant (the same) anywhere on the line.

Taking any to points on the line point (5, 200) and (10, 400)

Slope = change in y-coordinates / change in x-coordinates

change in y-coordinate = 400 - 200 which is 200

change in x-coordinate = 10 - 5 = 5

slope = 200/5 which is 40

As per the unitary method, the number of tulip were 21.

Unitary method:

In algebra, unitary method defines how to find the value of a unit from the value of a multiple and the value of a multiple from the value of a unit.

Given,

Here we have There were 35 bunches of rose and tulip. Each bunch had 12 of the roe flower. There 7 more bunches of tulip than rose.

Now we need to find how many tulip were there.

Let number of bunches of roses be x.

And then the number of bunches of tulips will be x + 7

The total number of bunches of flowers = 35                                                                          

So, it can be written as,

=> x + x + 7 = 35

When we simplify this one then we get,

=> 2x + 7 = 35

Now, we have to subtracting both sides by 7

=> 2x = 28

Then dividing both sides by 2

=> x = 14

So, the number of bunches of roses = 14

Then the number of bunches of tulips = 14 + 7 = 21
