6r%2B7=13%2B7r Start with the given equation.


6r=13%2B7r-7 Subtract 7 from both sides.


6r-7r=13-7 Subtract 7r from both sides.


-r=13-7 Combine like terms on the left side.


-r=6 Combine like terms on the right side.


r=%286%29%2F%28-1%29 Divide both sides by -1 to isolate r.


r=-6 Reduce.

Answer:

So the solution is r=-6
