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

Let's solve your equation step-by-step.

5(2x−8)+15=−15

Step 1: Simplify both sides of the equation.

5(2x−8)+15=−15

(5)(2x)+(5)(−8)+15=−15 (Distribute)

10x+−40+15=−15

(10x)+(−40+15)=−15 (Combine Like Terms)

10x+−25=−15

10x−25=−15

Step 2: Add 25 to both sides.

10x−25+25=−15+25

10x=10

Step 3: Divide both sides by 10.

10x /10 = 10 /10

Answer: x=1

Answer 2

according to pemdas, the first step is parentheses. multiply 2x and -8 by 5. the equation is now 10x-40+15=-15. add -40 and 15, which is -25. the equation is now 10x-25=-15. add -25 to -15 and you will get 10. the equation now looks like 10x=10. the final answer is x=1
