Answer:
r = -10
Step-by-step explanation:
We want to isolate r on one side so we can know what it's equal to. I'll start by subtracting 3 from both sides.
3 + 5r = -47
5r = -50
Now we can divide both sides by 5 to completely isolate our variable.
5r = -50
r = -10
We can go back and check our work by replacing r with -10:
3 + 5(-10) = -47 ?
3 + -50 = -47?
-47 = -47
