    y=x+8

    Move + 8 to the other side. Sign changes from + 8 to - 8.

    y-8=x+8-8

    y-8=x

    x=y-8 or x=-8+y

    Answer: x=y-8 or x=-8+y

    Answer: B) x=y-8.

    Explanation: to solve this problem we need to substract eight from both sides of the equation, in this way we isolate the x, the procedure is shown as follows:

    y=x+8

    y-8=x+8-8

    y-8=x

    so the answer is the corresponding to option B:

    x=y-8
