Uhhhh... well i need help with this algebra but i kinda need it explained as well...meaning if you can help please explain what you did because i have no idea how to do this kind of problem
r+3
 = 1
12
i need to know what r is
12

r+3
 = 1
12
Multiply both sides by 12.
r + 3 = 12
Subtract 3 from both sides.
r = 9
__________________________
You can prove it by substituting 9 for r in the original equation.
12/12 = 1 
OHHHH i get it i wasn't sure if i was supposed to mess with the 3 because ya know how with some problems you don't mess with the number next to the variable soo yeah thanks!:)
(P.S. Thanks you were an angel sent from the math heaven!!lol) 
You're welcome (polishing my halo)! :)
