u = 7
Step 1: Common denominators: LCM of 7 and 2 is 14
2u + 14/14 - 7u + 7/14 = -2
Step 2: Put everything over 14
2u + 14 - (7u + 7)/14 = -2
Step 3: Combine like terms: 2u - 7u = -5u 14 - 7 = 7
-5u + 7/14 = -2
Step 4: Multiply both side by 14 (this cancels out the 14 on the left side of the equation)
-5u + 7 = -28
Step 5: Subtract 7 from both sides.
-5u = -35
Step 6: Divide both sides by -5
u = 7

This is my step-by-step explanation for solving this problem:
Original setup: (u+7)/7 - (u+1)/2 = -2
Take common denominator of 2 and 7 (14) and multiply each element except for the current equation value (-2) accordingly: (2u+14)/14 - (7u+7)/14 = -2
Subtract the numerators: (-5u+7)/14 = -2
Multiply both sides by 14 so as to remove the denominator: -5u + 7 = -28
Subtract 7 from both sides so as to remove the second element: -5u = -35
Divide both sides by -5 so as to isolate the variable 'u':
u = 7
7 is the final value of the variable 'u'.

u= -18
u plus 8 over 5 = -2
-18+8=10 divided by 5 = -2

use parentheses to differentiate and I might be able to help. Is it (u + 7)/7 or u + (7/7), for example?
