Answer:
x = 9
Explanation:
We start by simplifying by distribution.
-2 -1(5x + 1) = 6(-x + 1)
Then we distribute by multiplying the outside term with each of the internal ones.
-2 + (-5x - 1) = (-6x + 6)
Open up the parentheses
-2 - 5x - 1 = -6x + 6
Simplify
-5x - 3 = -6x + 6
isolate x by adding like terms:
-5x +6x - 3 = -6x +6x +6
Simplify:
x - 3 = 6
Isolate x:
x = 9
