Answer:
no solution
Explanation:
if you were to graph this you would have two parallel lines, which indicates that there will be no solution
if you don't have a calculator you can get an answer but simplifying and isolating your terms.
First you would combine your like terms on the left and right side- giving you 3r+6=3r+4
Then you would subtract 6 from both sides- giving you 3r=3r-2
Next you would subtract 3r from both sides- giving you 0=-2
