Answer:

B = 4, (y + 4)(y - 4)

Step-by-step explanation:

So both terms are perfect squares. So we want to factor using the difference of squares formula wher a^2 - b^2 = (a + b)(a - b)

a = y and b = 4

Therefore

(y + 4)(y - 4)

To see which option is the most accurate one, we will verify all the options to see which is correct.

Option A (Correct/Incorrect)

Option A (Reasoning):

In this step, we can see that 3/4 was added to both sides. This can only mean that the property used here is the Addition property of Equality.

Option B (Correct/Incorrect)

Option B (Reasoning):

In this step, subtraction has not been used. It has been clearly stated that 3/4 was added to both sides.

Option C (Correct/Incorrect)

Option C (Reasoning):

In this step, multiplication has not been used. It has been clearly stated that 3/4 was added to both sides.

Option D (Correct/Incorrect)

Option D (Reasoning):

In this step, division has not been used. It has been clearly stated that 3/4 was added to both sides.

Option A is correct.

Addition property of equality is  applied in the first step of equation x/4-3/4=16.

Two or more expressions with an Equal sign is called as Equation.

The given equation is x/4-3/4=16

x divided by four minus three divided by four equal to sixteen.

The first step to solve this equation as

x/4-3/4+3/4=16+3/4

Which means we have added 3/4 on both sides of the equation.

As per the addition property of equality, when we add the same number to both sides of an equation then the two sides remain equal.

So we have used the  addition property of equality

Hence,  addition property of equality is  applied in the first step of equation x/4-3/4=16.

An expression for x in terms of a and b is y = b - 2x and an expression for y in terms of a and b is y = 2a - b.

A numerical expression is a mathematical statement written in the form of numbers and unknown variables. We can form numerical expressions from statements.

Given, A system of equations x + y = a and 2x + y = b.

Now,

x + y = a.

x = a - y and y = a - x.

2x + y = b.

2x = b - y.

x = (b - y)/2.

y = b - 2x.

An expression for x in terms of a and b is,

x + y = a

x + b - 2x = a.

- x = a - b.

x = b - a.

An expression for y in terms of a and b is,

2(a - y) + y = b.

2a - 2y + y = b.

2a - y = b.

- y = b - 2a.

y = 2a - b.

Answer: w = 9

Isolate the variable by dividing each side by factors that don't contain the variable. First, we rearrange the terms.

18 + 4w = 6w

4w + 18 = 6w

Now we subtract 18 from both sides.

When we simplify, we get that w = 9.

Step-by-step explanation:

Hope this helps =)

Answer:

w = 9

Step-by-step explanation:

Rearrange terms

4w + 18 = 6w

Subtract 18 from both sides of the equation

4w+18-18 = 6w -18

Simplify

4w=6w-18

Subtract 6w from both sides of the equation

4w-6w=6w-18-6w

Simplify

-2w=-18

Divide both sides of the equation by the same term

-2w = -18/-2

Simplify

w = 9
