2x+16=0
Variable x cannot be equal to any of the values -2,2 since division by zero is not defined. Multiply both sides of the equation by \left(x-2\right)\left(x+2\right).
2x=-16
Subtract 16 from both sides. Anything subtracted from zero gives its negation.
x=\frac{-16}{2}
Divide both sides by 2.
x=-8
Divide -16 by 2 to get -8.
