I'll show you the working to show u how to do it
A-
5x-4=3x+5
2x-4=5
2x=9
so x=4.5

B-
7x-9=2x+21
5x-9=21
5x=30
x=6

C-
20/25
(x both sides by 4 because 25x4 is 100)
= 80/100
= 80%

cba to do the rest i'm tired,, why aren't you doing it urself?

These don’t take long to solve, if you can’t do them then you should learn.
