Solving equation
Posted:
Oct 10, 2004 9:45 PM


Hello  I am new to pre/algebra, and I have difficulty understanding how to do equations with variables on both sides.
Like this:
7r  1 = 5r  13
I get rid of one and have:
7r = 5r  12
Then I get rid of 5r and have:
3r = 12
r = 4 ?
Could someone tell me where I go wrong with this? Appreciate any response.
