Answer
x=-1
Work Step by Step
Simplifying
3(x + 4) + 3x = 6
Reorder the terms:
3(4 + x) + 3x = 6
(4 * 3 + x * 3) + 3x = 6
(12 + 3x) + 3x = 6
Combine like terms: 3x + 3x = 6x
12 + 6x = 6
Solving
12 + 6x = 6
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-12' to each side of the equation.
12 + -12 + 6x = 6 + -12
Combine like terms: 12 + -12 = 0
0 + 6x = 6 + -12
6x = 6 + -12
Combine like terms: 6 + -12 = -6
6x = -6
Divide each side by '6'.
x = -1
Simplifying
x = -1
