10r-60=9r solve for r

r = 60

Step-by-step explanation:

With any equation with a variable, you want to isolate the variable to find its actual value. I'll show you a step by step:

10r - 60 = 9r

Subtract 9r from both sides:

10r - 9r - 60 = 9r - 9r

Simplify:

r - 60 = 0

Add 60 to both sides to isolate r:

r - 60 + 60 = 0 + 60

Simplify:

r = 60

The answer is R=60 ... yu have to subtract 10r from both sides which then leaves you with - 60=-1r. From that, you divide both sides by - 1 which ends to giving your answer which is r=60
