Step-by-step explanation:
2x + 6 =
Simplifying
2x + 6 = 0
Reorder the terms:
6 + 2x = 0
Solving
6 + 2x = 0
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-6' to each side of the equation.
6 + -6 + 2x = 0 + -6
Combine like terms: 6 + -6 = 0
0 + 2x = 0 + -6
2x = 0 + -6
Combine like terms: 0 + -6 = -6
2x = -6
Divide each side by '2'.
x = -3
Simplifying
x = -3
