2(2x - 7) - 16 = 3 (-x - 7) - 11
= 4x - 14 - 16 = -3x -21 - 11
= 4x - 30 = -3x - 32
What do you do frok there?
2(2x-7)-16=3(-x-7)-11
After getting rid of the ()
4x-14-16=-3x-21-11
Where do I go from here?

4x - 30 = -3x - 32
add 3x to both sides
7x - 30 = -32
add 30 to both sides
7x = -2
divide by 7
x = -2/7
add 3x to both sides
7x - 30 = -32
add 30 to both sides
7x = -2
divide by 7
x = -2/7
