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
Answered by Ms. Sue
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
