    Simplifying

    8x + - 12 = 9x + - 4 + x

    Reorder the terms:

    -12 + 8x = 9x + - 4 + x

    Reorder the terms:

    -12 + 8x = - 4 + 9x + x

    Combine like terms: 9x + x = 10x

    -12 + 8x = - 4 + 10x

    Solving

    -12 + 8x = - 4 + 10x

    Solving for variable 'x'.

    Move all terms containing x to the left, all other terms to the right.

    Add '-10x' to each side of the equation.

    -12 + 8x + - 10x = - 4 + 10x + - 10x

    Combine like terms: 8x + - 10x = - 2x

    -12 + - 2x = - 4 + 10x + - 10x

    Combine like terms: 10x + - 10x = 0

    -12 + - 2x = - 4 + 0

    -12 + - 2x = - 4

    Add '12' to each side of the equation.

    -12 + 12 + - 2x = - 4 + 12

    Combine like terms: - 12 + 12 = 0

    0 + - 2x = - 4 + 12

    -2x = - 4 + 12

    Combine like terms: - 4 + 12 = 8

    -2x = 8

    Divide each side by '-2'.

    x = - 4

    Simplifying

    x = - 4

    We need to add like terms, meaning add the x's together and add the regular numbers together.

    So if we add the x's together, - 8x+9x = 1x.

    Then when we add the numbers together, - 12+4 = - 8.

    Combine our two sums and we get x-8 as the final answer.
