Question

Choose the answer based on the most efficient method as presented in the lesson. If the first step in the solution of the equation -8 - 7x = -5x - 10 is "add 10," then what should the next step be? add 5x add 7x add 8

Answer 1

add 7x

Explanation:

This would be the answer because if you have already added 10 to one side of the equation and have erased the constant on the right side, you would need to do something to erase the variable on the other side, hence, add 7x. This makes the equation balanced.

Answer 2

You would add 7x and then finish out the equation
