Answer :
Answer:
60
Step-by-step explanation:
First, we add all like terms on each side of the equation.
To the left, we can add 6 and 48, to get 54.
Now we must move the other like term from the left side to the right side.
To get rid of -6, (because the negative sign is connected to the 6 now), we add 6.
What we do to one side we must do to the other!
54 + 6 = 60.
On the left side, we still have r, making the equation
r = 60.
