16=8^{2}+2\left(-2\right)x
Calculate 4 to the power of 2 and get 16.
16=64+2\left(-2\right)x
Calculate 8 to the power of 2 and get 64.
16=64-4x
Multiply 2 and -2 to get -4.
64-4x=16
Swap sides so that all variable terms are on the left hand side.
-4x=16-64
Subtract 64 from both sides.
-4x=-48
Subtract 64 from 16 to get -48.
x=\frac{-48}{-4}
Divide both sides by -4.
x=12
Divide -48 by -4 to get 12.
