  • x/2 _ y/3 = 2. x 1/2
    x/4 + y/2 = 3. x 1

    1/4x _ 1/6y = 1
    1/4x + 1/2y = 3
    ____________ _
    _ 4/6y = _ 2
    y = _ 2 : _ 4/6
    y = _ 2 x _ 6/4 = 12/4
    y = 3
    1/2x _ 1/3y = 2
    1/2x _ ( 1/3 x 3) = 2
    1/2x _ 1 = 2
    1/2x = 2 + 1
    1/2x = 3
    x = 3 : 1/2
    x = 3 x 2/1
    x = 6
    ( hp y = 3
    x = 6
