5 and 4 have no common factors until they are multiplied by each other. So if you were to convert your existing measurements, you would do the following.
(3/4) x (5/5)
(2/5) x (4/4)
Giving you 15/20 and 8/20
3(-4x+5)=12 (Divide by 3 on both sides)
-4x+5=4 (Add -5 to both sides)
-4x=-1 (Divide by -4 on both sides)
x=1/4
Check:
3(-4(1/4)+5)=12
3(-1+5)=12
3(4)=12
So, your final answer is x=1/4

Step-by-step explanation:
The answer is 5g - 8 is your answer
I would assume 1/5 is your answer. As 1/5+1/5+1/5+1/5+1/5 = 5/5 which is 1.
