-9/4v + 4/5 = 7/8;
First, you subtract 4/5 from each side to have variable v on a side and numbers on the other:
-9/4v = 7/8 - 4/5;
-9/4v = 35/40 - 32/40;
-9/4v = 3/40;
Then you divide each side to get the variable v alone on a side, and one number on the other:
V= (3/40) / (-9/4);
Dividing to fractions is equal to multiplying the first one by the inverse of the second:
V= (3/40) * (-4/9);
V= -12/360;
V= -1/30;
You can re-check your answer (very important):
(-9/4)*(-1/30)+4/5=7/8;
The answer has been approved.
Hope this helps! :)

Answer: −22w−25
Step-by-step explanation: Distribute:
=−22w+−5+5w+(−5)(w)+(−5)(4)
=−22w+−5+5w+−5w+−20
Combine Like Terms:
=−22w+−5+5w+−5w+−20
=(−22w+5w+−5w)+(−5+−20)
=−22w+−25
