    look at the coefients

    coffients of x are - 6 and 6, so if we add them together, we can get 0x and cancel them

    add the equations

    6x+4y=32

    -6x+4y=8 +

    0x+8y=40

    8y=40

    divie by 8 both sides

    y=5

    subsitute back

    6x+4y=32

    6x+4 (5) = 32

    6x+20=32

    6x=12

    x=2

    the ordered pair in (x, y) form is (2,5)
