    X=-5y/13+90/13, Y=-13x/5+18

    Step-by-step explanation:

    You need to solve the equation for X and Y.

    Solving for X:

    13x+5y=90

    Subtract 5y: 13x=-5y+90

    Divide by 13: x=-5y/13+90/13

    --

    For Y:

    13x+5y=90

    Subtract 13x: 5y=-13x+90

    Divide by 5: y=-13x/5+90/5

    (Simplifies to - 13x/5+18)
