Answer:


-\frac38 or -0.375

Explanation:

Hello!

We can solve for "u" by isolating the variable.

First, expand the parentheses.

Solve for u

  • 5(u-9) - 3 = -6(-4u+7) - 3u
  • 5u - 45 - 3 = 24u - 42 - 3u
  • 5u - 48 = 21u - 42
  • 5u - 6 = 21u
  • -6 = 16u
  • -6/16 = u
  • -3/8 = u

u is -0.375.
