9x+5y=-42
-2x+y=22
Find the ordered pairs

  • algebra - ,

    (multiplying the second equation by -5 to cancel the y's)
    9x+5y=-42
    10x-5y=-110
    19x=-152
    x=-8
    Put that in either ORIGINAL equation to solve for y, and then your ordered pair would be (-8, y), replacing y with whatever you get for y.
