    working with multiple equations to find an equal multiple of variables requires solving and subsitution.

    First, pick x or y, and one equation, and solve the chosen equation for the chosen variable.

    The term that x is equal to can be substituted in for x in the leftover equation to find a specific y, which can then be substituted into either equation to find x.
