5(4r3c)2(7r9c)=0 solve for r
This is all I know how to do and don't know if it's even right. Or what to do from here.
5(4r3c)2(7r9c)=0 solve for r
20r15c14r11c=0
6r26c=0

see the post above this, follow the same steps

this is the steps:
20r15c14r+18c=0
6r+3c=0
so for my final answer I got r=c/2 is that correct? 
close ...
from your second last line
6r + 3c = 0
6r =  3c
r = c/2
btw, I am glad you caught your error in the steps of your original at the top,
where did the 11c come from?
