    Because you want to solve for x last, so multiply everything by 2 first, and then add 5 to everything.

    A negative multiplied by a positive is a negative.

    -3 * 2, is saying, "negative 3 sets of two."

    No, it's saying, "x - 3," "Ex take away three."

    I am not allowed to give you the answer, but the equation is now: x - 6 = -10 Add six

    the -3 can be seen as +(-3), so you work with an negative number. The problem is "how you isolate x?"
