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
