8y-9y= -21
write two equations that have your two intergers as a solution.Addition and subtraction methods

  • college algebra - ,

    You have already written two equations. What do you mean by "Your" (my) two integers?

    Shouldn't your second equation be 8x - 9y = -21? The way you have written it,-7 = -21, so y = 21

    Why don't you just ask for the solution to your two equations? (I assume you meant the first y to be x in the second equation)
    24x + 28y = 212
    24x - 27y = -63
    Subtract the second from the first
    55y = 275
    y = 5
