Question

-7-3(-8x+8)=-4(-4x+2)-8

Answer 1

-7-3(-8x+8)=-4(-4x+2)-8
-10(-8x+8) = 16x-8-8
80x-80=16x-16
64x=64
x=1

is this correct?

Answer 2

No^^. You can't combine the -7 and the -3 AND THEN MULTIPLY. It goes against order of operations. You want to distribute the -3 then combine. It should read like this:
\[-7+24x-24=16x-8-8\]
\[24x-31=16x-16\]
\[8x=15\]
\[x=\frac{15}{8}\]
