Simplifying
2x + 3 + 7x = - 24
Reorder the terms:
3 + 2x + 7x = - 24
Combine like terms: 2x + 7x = 9x
3 + 9x = - 24
Solving
3 + 9x = - 24
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-3' to each side of the equation.
3 + - 3 + 9x = - 24 + - 3
Combine like terms: 3 + - 3 = 0
0 + 9x = - 24 + - 3
9x = - 24 + - 3
Combine like terms: - 24 + - 3 = - 27
9x = - 27
Divide each side by '9'.
x = - 3
Simplifying
x = - 3
