Question

Solve for u.
5(u-9)-3=-6(-4u+7)-3u

Answer 1

`-\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.
