10x - 2x + 6 = 3x - 9
Simplifying 10x + -2x + 6 = 3x + -9
Reorder the terms:
6 + 10x + -2x = 3x + -9
Combine like terms: 10x + -2x = 8x
6 + 8x = 3x + -9
Reorder the terms:
6 + 8x = -9 + 3x
Solving
6 + 8x = -9 + 3x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-3x' to each side of the equation.
6 + 8x + -3x = -9 + 3x + -3x
Combine like terms: 8x + -3x = 5x
6 + 5x = -9 + 3x + -3x
Combine like terms: 3x + -3x = 0
6 + 5x = -9 + 0
6 + 5x = -9
Add '-6' to each side of the equation.
6 + -6 + 5x = -9 + -6
Combine like terms: 6 + -6 = 0
0 + 5x = -9 + -6
5x = -9 + -6
Combine like terms: -9 + -6 = -15
5x = -15
Divide each side by '5'.
x = -3
Simplifying
x = -3
