A piont on a graph that works for x-y=8and x+y=-2

  • Algerbra -

    This is a system of equations.

    The easiest way to solve would be the elimination method because it is already set up; if you add the equations, the y cancels out and gives you:
    Given x you can find y in any equation above; x-y=8
    Substitute the 3: 3-y=8
