  u = -45/7 = -6 3/7

Step-by-step explanation:

It can work well to eliminate fractions first. Here, we can do that by multiplying by the product of their denominators: 12.

  -4u -48 = 3u -3

 -45 = 7u . . . . . . . . add 3+4u

  -45/7 = u . . . . . .  divide by the coefficient of u

Check

(-1/3)(-45/7) -4 = (1/4)(-45/7) -1/4

  15/7 -4 = -45/28 -7/28

  -13/7 = -52/28 . . . true
