r+2=11-2r

We move all terms to the left:

r+2-(11-2r)=0

We add all the numbers together, and all the variables

r-(-2r+11)+2=0

We get rid of parentheses

r+2r-11+2=0

We add all the numbers together, and all the variables

3r-9=0

We move all terms containing r to the left, all other terms to the right

3r=9

r=9/3

r=3
