    (x, y) = (0.5, 1.5) = (1/2, 3/2)

    Step-by-step explanation:

    these are tricky you have to manipulate the equations to get the x and y by itself and then solve for that

    3x+y=3

    x+y=2 (multiply this equation by 3) =

    3x+3y=6

    now subtract the equations

    (3x+3y=6) - (3x+y=3) = 2y=3 so y = 3/2 or 1.5

    now plug in the y value for one of the equations and solve for x

    x + 3/2 = 2

    x = 1/2 or 0.5
