    You have to do like terms

    Step-by-step explanation:

    12x+10+8+8x

    12x+8x = 20x

    10+3 = 13

    your answer would be

    20x+10

    Simplifying

    12x + 10 + 3 + 8x = 0

    Reorder the terms:

    10 + 3 + 12x + 8x = 0

    Combine like terms: 10 + 3 = 13

    13 + 12x + 8x = 0

    Combine like terms: 12x + 8x = 20x

    13 + 20x = 0

    Solving

    13 + 20x = 0

    Solving for variable 'x'.

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

    Add '-13' to each side of the equation.

    13 + - 13 + 20x = 0 + - 13

    Combine like terms: 13 + - 13 = 0

    0 + 20x = 0 + - 13

    20x = 0 + - 13

    Combine like terms: 0 + - 13 = - 13

    20x = - 13

    Divide each side by '20'.

    x = - 0.65

    Simplifying

    x = - 0.65
