Solve for x:<br> I need a answer with an explanation. Algebra 1

kirill115 [55]

Answer: x = -1

Step-by-step explanation:

You need to convert to the same base

$\frac{1}{16} = \frac{1}{2^{4} } = 2^{-4}$

$2^{-4} = 2^{-2x-6}$

For these values to be equal, the exponents have to be equal

-4 = -2x - 6

2 = -2x

x = -1
