  1. y-1/x+3=-3/4

    y-1/x+ 1/x + 3-3 = -3/4 + 1/x -3
    y - 0 + 0 = -3/4 - 3 + 1/x
    y = (-3 - 12)/4 + 1/x
    y = -15/4 + 1/x

  2. Assuming the usual carelessness with parentheses, I see it as follows:

    (y-1)/(x+3) = -3/4
    y-1 = -3/4 (x+3)
    y = -3/4 (x+3) + 1
    y = -3/4 x - 5/4
    y = -(3x+5)/4
