Answer:
x = 0
Step-by-step explanation:
First, multiply the -3 by two (<u>-3</u>(x + 2)<u>2</u> + 4 = -8) -- -6(x+2)+4 = -8.
Then, subtract 4 from both sides (-6(x+2)+<u>4</u> = -8) -- -6(x+2) = -12
After that, divide both sides by -6 (<u>-6</u>(x+2) = -8) -- 
Simplify -- x+2=2
Subtract 2 from both sides (x+<u>2</u>=2) -- x = 0
Hope this helped! Good luck with future math problems :)
