Given u/7 - 1 = 7 and plugging in values for u,
For u = 28; 28/7 - 1 = 4 - 1 = 3; No
For u = -49; -49/7 - 1 = -7 - 1 = -8; No
For u = 42; 42/7 - 1 = 6 - 1 = 5; No
For u = 0; 0/7 - 1 = -1; No
Another way to find out which value would be a solution to u/7 - 1 = 7 is to solve for u.
u/7 - 1 = 7
u/7 = 7 + 1
u/7 = 8
u = 8*7
u = 56
The only solution to this equation is when u = 56.

Answer:
27
Step-by-step explanation:
3v+6=5v-8
3v+14=5v
14=2v
v=7
3*7+6
21+6
27
u were right on 7 u just need to plug it into the equation
2(x + 11) + 7x = 9x - 22
mutiply the bracket by 2
(2)(x)= 2x
(2)(11)= 22
2x+22+7x=9x-22
2x+7x+22= 9x-22 ( combine like terms)
9x+22= 9x-22
move 9x to the left side
sign changes from +9x to -9x
9x-9x+22= 9x-9x-22
0+22= 0-22
22= -22
Answer:
C. no real solutions
