Answer:
-1/7
Step-by-step explanation:
First you need to understand negative exponents. Baisically it means 1/the number to the positive power. For this problem, it's
1/(-7)^1
-7^1=-7
(-7)^-1=-1/7
So first u need to get the variables separate from the constants so add 8 to both sides. then u get 4x = 4 then u can divide each side by 4 to get x alone.
so the answer is
x = 1
