Answer: x = - 9
Step-by-step 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

4. (2x - 6) = 10x - 6
4.2x - 4.6 = 10x - 6
8x - 24 = 10x - 6
-24 + 6 = 10x - 8x
-18 = 2x
x = - 9
