    So you need to first cancel out x so multiply - 1 to one of the equations i'm gong to pick the second one so now it is 7x-5y=22 and - 7x+9y=-6 then add so 4y=16 so y=4

    You can do this by taking away the second equation from the first to get rid of the x terms so:

    7x - 7x = 0

    -5y - - 9y = - 5y + 9y = 4y

    22-6 = 16

    So you are left with the equation:

    4y = 16

    Divide both sides by 4 to find y

    y = 4
