$x=-\frac{3}{4}$

Step-by-step explanation:

Given Equation:

$(-12x+6)+(4x-12)\\$

Taking the standard form of the equation to solve for 'x':

(-12x+6)+(4x-12)=0

Opening the brackets:

-12x+6+4x-12=0

Adding the like terms:

$-8x+6-12=0\\\\-8x-6=0$

Adding '6' both sides:

-8x=6

Dividing by '-8' both sides:

$x=\frac{6}{-8} \\\\x=-\frac{3}{4}$
