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}

So

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

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

-4 = -2x - 6

2 = -2x

x = -1

−3x + y = 4,<br><br> −9x + 5y = −1<br> find x and y
katrin [286]

Answer:

9x - 3y = -12

x = -21/6 = -7/2

(-7/2, -13/2)
