  1. 1/2x+1/3y=5
    1/4x+1/3y=4
    First I want to get rid of the fractions..multiply the first equation by 6 and the second one by 12.
    3x+2y=30 (1)
    3x+4y=48 (2)
    Now multiply the first equation by -1.
    -3x-2y=-30
    3x+4y=48
    Add the equations together.
    2y=18
    Solve for y, put it back into (1) or (2) to solve for x.
