6r+7=13+7r first you subtract 7 to 13 -7 -7. Then you'll get 6r=6+7r then you just subtract 7r to 6r 1r=6 R=6

Take the 7 and subtract it on both sides. Then you have 6r=6+7r
Now take 7r and subtract it on both sides. With that done you have -r=6
Divide both sides by -1 then your answer is there r= -6
