Answer: x = -9 
Explanation:
Simplifying 
4(2x + -6) = 10x + -6 
 
Reorder the terms: 
4(-6 + 2x) = 10x + -6 
(-6 * 4 + 2x * 4) = 10x + -6 
(-24 + 8x) = 10x + -6 
 
Reorder the terms: 
-24 + 8x = -6 + 10x 
 
Solve
-24 + 8x = -6 + 10x 
 
Solving for variable 'x'. 
 
Move all terms containing x to the left, all other terms to the right. 
 
Add '-10x' to each side of the equation. 
-24 + 8x + -10x = -6 + 10x + -10x 
 
Combine like terms: 8x + -10x = -2x 
-24 + -2x = -6 + 10x + -10x 
 
Combine like terms: 10x + -10x = 0 
-24 + -2x = -6 + 0 
-24 + -2x = -6 
 
Add '24' to each side of the equation. 
-24 + 24 + -2x = -6 + 24 
 
Combine like terms: -24 + 24 = 0 
0 + -2x = -6 + 24 
-2x = -6 + 24 
 
Combine like terms: -6 + 24 = 18 
-2x = 18 
 
Divide each side by '-2'. 
x = -9 
 
Simplifying 
x = -9
