Question

An equation is shown below:

5(2x - 8) + 15 = -15

Write the steps you will use to solve the equation and explain each step.

Answer 1

You would Use the order of operations

Explanation:

first solve what's inside of the parentheses (2x - 8)

then solve multiplication 5 × (2x - 8)

and finally solve addition + 15

and that will equal -15

Answer 2

x=1

Explanation:

5(2x - 8) + 15 = -15

Distribute

10x -40 +15 = -15

Combine like terms

10x -25 = -15

Add 25 to each side

10x -25+25 = -15+25

10x =10

Divide by 10

10x/10 = 10/10

x=1
