Answer:

4

Step-by-step explanation:

-5+-6 = -11

-2x-3=-11

2x=8

x=4

Answer 2

Answer:

4

Step-by-step explanation:

$(\frac{3}{4})^{-5}* (\frac{3}{4})^{-6} = (\frac{3}{4})^{-2x-3}\\\\(\frac{3}{4})^{-5-6} = (\frac{3}{4})^{-2x-3}\\\\(\frac{3}{4})^{-11} = (\frac{3}{4})^{-2x-3}$       Add raised to power -3 to both sides

$(\frac{3}{4})^{-8} = (\frac{3}{4})^{-2x}$                       Divide raised to power 2 to both sides

$(\frac{3}{4})^{-4} = (\frac{3}{4})^{-x}\\x = 4$
