Question

Solve for x. Show or explain your work.

Then, verify that your solution is correct.

-15 = 2x + 1

Answer 1

-8 = x

Explanation:

-15 = 2x + 1

-1 - 1 Subtract 1 from both sides

-16 = 2x Divide both sides by 2

-8 = x

To make sure this answer is correct, plug it into the equation to see if it works.

-15 = 2(-8) + 1 Multiply

-15 = -16 + 1 Add

-15 = -15
