-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!
