2\left(6-8\times 8\right)=x-4\times 4\times 8
Multiply 2 and 4 to get 8.
2\left(6-64\right)=x-4\times 4\times 8
Multiply 8 and 8 to get 64.
2\left(-58\right)=x-4\times 4\times 8
Subtract 64 from 6 to get -58.
-116=x-4\times 4\times 8
Multiply 2 and -58 to get -116.
-116=x-16\times 8
Multiply 4 and 4 to get 16.
-116=x-128
Multiply 16 and 8 to get 128.
x-128=-116
Swap sides so that all variable terms are on the left hand side.
x=-116+128
Add 128 to both sides.
x=12
Add -116 and 128 to get 12.
