Sorry for taking so long, it wont let me type a while ago. I have it all fix now hehe. I took a picture of my work, ask me if you still don’t understand.
26 would 130% of 26%.
20 would be 100% of itself leading us to X being 130%.
That brings us to two equations of 20=100% and x=130%
20/x=100%/130%
20/x=100/130
(20/x)*x=(100/130)*x
20=0.769230769231*x
26/0.769230769231=x
26=x therefor x=26
