Answer:

r = -6

Step-by-step explanation:

basically send the letters on one side (preferably the left) of the = sign... and the numbers on the other side. Remember when you pelting things across the equal sign, you have to switch the signs... meaning positive (+) will become negative (-) or vice versa...

6r + 7 = 13 + 7r

6r - 7r = 13 - 7

-1r = 6

r = -6
