Answer:

Step-by-step explanation:

1. Write the equation

2. Multiply the 8 with what’s in the parenthesis so you would have 8r+32

3. Plus the opposite so you’d have +(-3)=85

4. Subtract 32 from 85 so your left with 53

5. Add -3 to 53 to get 56

6. You’ll be left with 8r=56

7. Divide 56 by 8

8. r=7
