Question

What is the solution to this equation?

Answer 1

Answer: x = 12

Step-by-step explanation:

The given equation is expressed as

5х+9 - 3х= 18 + 15

5x - 3x + 9 = 33

2x + 9 = 33

The first step is to make the terms each term containing x to be on the left hand side of the equation and the constants to be on the right hand side of the equation. Therefore, we would subtract 9 from the left hand side and the right hand side of the equation.

It becomes

2x + 9 - 9 = 33 - 9

2x = 24

Dividing the left hand side and the right hand side of the equation by 2, it becomes

2x/2 = 24/2

x = 12

Answer 2

Answer:

C. x = 12

Step-by-step explanation:

5(12) + 9 = 69 - 3(12) = 33

18 + 15 = 33
