Answer:
x = -10
Explanation:
2(x + 3) = x + -4
Reorder the terms:
2(3 + x) = x + -4
(3 * 2 + x * 2) = x + -4
(6 + 2x) = x + -4
Reorder the terms:
6 + 2x = -4 + x
Solving
6 + 2x = -4 + x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-1x' to each side of the equation.
6 + 2x + -1x = -4 + x + -1x
Combine like terms: 2x + -1x = 1x
6 + 1x = -4 + x + -1x
Combine like terms: x + -1x = 0
6 + 1x = -4 + 0
6 + 1x = -4
Add '-6' to each side of the equation.
6 + -6 + 1x = -4 + -6
Combine like terms: 6 + -6 = 0
0 + 1x = -4 + -6
1x = -4 + -6
Combine like terms: -4 + -6 = -10
1x = -10
Divide each side by '1'.
x = -10
