simplify the expression by combining like terms
r + 2s + 3r

Well since both the 'r's are like terms, you'd combine them, and don't forget that there is a 1 in front of each variable, so you'd add 3 + 4 and have 4r.
OH sorry typo!
3 +1 and you'd have 4r! sorry!
3 +1 and you'd have 4r! sorry!
How do you combine the r's?
Nicole, Thanks but I do not understand
how do you combine the r's?
how do you combine the r's?
you would combine the r's just by adding them together, because they are the same variable. The first r in the equation doesn't have a number with it, right? So since it isn't attatched to a number, pretend that there is an invisible 1 in front of it. So when you add the two r's together then you get 4r right? So pretend instead that the equation reads:
1r + 2s + 3r
1r + 2s + 3r
4r + 2s
exactly =)
