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.
3x-7>2
add 7 to both sides: 3x>9
divide both sides by 3: x>9

Answer:
1
Step-by-step explanation:
1. expand the terms on the right side of the equation: 6=2y+4
2. subtract 4 from both side: 2=2y
3. divide both side by 2: 1=y
