    x = - 8

    Step-by-step explanation:

    to solve this kind of problem is very simple, just be very careful about the negative and positive signs.

    -7+2x = - 6x - 71

    we will collect the like terms or simply say that you will combine the like terms

    we have,

    -7 + 2x + 6x = - 71

    2x + 6x = - 71 + 7

    8x = - 64

    divide both sides by 8

    8x/8 = - 64/8

    x = - 8

    Step-by-step explanation:

    -7 + 2x = - 6x - 71

    Cancel out the equation to add on to the other side. Anyway works.

    If you add or subtract a number from left to right, the other add or subtract needs to be right to left. Vise versa.

    -7 + 2x = - 6x - 71

    +7 + 6x = + 6x + 7

    -7 + 2x = - 6x - 71

    +7 + 6x = + 6x + 7

    Then you will get: - 8x = - 64

    Because X is not by itself, you want to divide the number by itself cancel out ONLY the number and not X. When you cancel out a number, it has to be applied to the whole equation and thus you will get - 64/-8 = Answer

    8x = - 64

    8 = 8

    X = - 8
