    6x + 19 + 3x + - 6 + 5x + - 15 = 180

    19 + - 6 + - 15 + 6x + 3x + 5x = 180

    19 + - 6 = 13

    13 + - 15 + 6x + 3x + 5x = 180

    13 + - 15 = - 2

    -2 + 6x + 3x + 5x = 180

    6x + 3x = 9x

    -2 + 9x + 5x = 180

    9x + 5x = 14x

    -2 + 14x = 180

    -2 + 14x = 180

    Solving for variable 'x'.

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

    Add '2' to each side of the equation.

    -2 + 2 + 14x = 180 + 2

    -2 + 2 = 0

    0 + 14x = 180 + 2

    14x = 180 + 2

    180 + 2 = 182

    14x = 182

    Divide each side by '14'.

    x = 13

    x = 13

    6x+19+3x-6+5x-15=180

    14x = 180 - 19 + 6 + 15

    14x = 182

    x = 182 : 14

    x = 13
