Answer 1

try to get the u’s on one side so for this to happen, you would subtract the four from both sides.
u - 4u = 7 - 4

combine like terms

-3u = 3

divide by -3

u = -1

Answer 2

U = -1

Explanation:

Combine U with -4U and you get -3.

-3u + 4 = 7

Subtract 4 from 7, you get 3.

Divide 3 by -3, you get -1.

U = -1
