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?

Answer 1

-8x-7x=-5x-10
Add or move the -10 to the other side
It becomes: -8+10-7x=-5x
Which then becomes: 2-7x=-5x
Add or move the -7x to the other side
It becomes: 2=-5x+7x
Which then becomes: 2=2x
