Solve for X
−3.5=−4.6x−5.1
Enter your answer as a fraction in simplest form in the box.
The solution of the expression will be;
⇒ x = - 8/23
What is an expression?
Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
The expression is,
⇒ - 3.5 = - 4.6x - 5.1
Now,
Solve the expression as;
The expression is,
⇒ - 3.5 = - 4.6x - 5.1
Solve for x as;
⇒ - 3.5 + 5.1 = - 4.6x
⇒ 1.6 = - 4.6x
⇒ -4.6x = 1.6
⇒ x = 1.6 / - 4.6
⇒ x = - 16/46
⇒ x = - 8/23
Thus, The solution of the expression will be;
⇒ x = - 8/23

What is Unitary Method?The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.
For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.
12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.
As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.
This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.
Given:
Case 1: Bus
Consumption/ 100Km= 301
and, for 250 Km= 301 /100 x 250
= 751
Case 2: Car
Total = 80 people
Total cars= 30/5 = 6
Consumption/ 100Km= 91
and, for 250 Km= 91 /100 x 250
= 22.51
Consumption by 6 cars = 6 x 22.51 = 1351
Difference between Gasoline Consumption = 1351-751 = 601
