    x= -1

    transpose all x to left hand side and the numbers to the right, when you transpose over the = sign the sign reverses

    -5x+6=x+12

    -5x -x = 12 - 6

    -6x = 6

    x = 6/-6

    x = -1

    -5x + 6=x + 12

    add 5x to both sides:

    -5x + 6 + 5x = x + 12 + 5x

    6 = 6x + 12

    subtract 12 from both sides:

    6 - 12 = 6x + 12 - 12

    -6 = 6x

    divide by sides by 6:

    -6/6 = 6x/6

    x = -1

    first I would group like terms

    -5x-x = 12-6

    (don't forget to change the signs)

    then do the math

    -6x = 6

    x=-1
