-3

Explanation:

First, use the distributive property of multiplication to distribute the -6 to all of the numbers in the parenthesis.

132 = 2x - 6(-2 + 7x)
132 = 2x + 12 - 42x

Combine Like Terms:

132 = 2x + 12 - 42x
132 = -40x + 12

Use the Additive Inverse:

132 = -40x + 12
120 = -40x

Use the Multiplicative Inverse:

120 = -40x
-3 = x

There's your answer!
