Answer:

u = -1

Step-by-step explanation:

5(u+1)-u=3(u-1)+7

distributive property

5u + 6 = 3u - 3 + 7

simplify

5u + 6 = 3u + 4

-3u on both sides

2u + 6 = 4

-6 on both sides

2u = -2

divide 2 on both sides

u = -1

5(u + 1) - u = 3(u - 1) + 7 \\ 5u + 5 - u = 3u - 3 + 7 \\ 5u - u + 5 = 3u  - 4 \\ 4u + 5 = 3u - 4 \\ 4u - 3u  =  - 4 - 5 \\ u =  - 9

sorry if this is not correct
