Question

Solve 8x − 2(x + 1) = 7x + 8. (5 points) 6 −6 −10 10

Answer 1

First, simplify the equation.
8x - 2x - 2 = 7x + 8
Now subtract 8 on both sides to get rid of the one on the right side.
8x - 2x - 10 = 7x
Solve the left side.
6x - 10 = 7x
Subtract 6x from both sides.
-20 = x
Therefore, x = -20.
