Answer:

r =10

Step-by-step explanation:

5(r + 3) = 3r + 35.

Distribute

5r+15 = 3r+35

Subtract 3r from each side

5r+15-3r = 3r+35-3r

Combine like terms

2r +15 = 35

Subtract 15 from each side

2r+15-15 =35-15

2r = 20

Divide by 2

2r/2 =20/2

r =10

5(r + 3) = 3r + 35
Remove parentheses
5r + 15 = 3r + 35
Move the terms
5r - 3r = 35 - 15
Collect like terms
2r = 20
Divide both sides
R = 10
