I have two equations that I need to solve using the elimination method the system is x = y = 9 and 2x - y = -3

  • Algebra - ,

    i think u wrote it incorrectly did u mean x+y= 9?? if so
    x +y= 9
    2x-y=-3
    3x = 6
    x = 2

    or
    x +y= 9 (-2) -2x-2y=-18
    2x-y=-3 2x- y=-3
    -3y=-21
    y=7
    u can use the elimination process to solve for both or u can solve for one and plug it in any one of the equations to solve for the other
