Question

R + 3 = 3 ( r - 5 )​

Answer 1

r +3=3r -15

r-3r= -15-3

-2r = -18

r=9

Answer 2

r =9

Explanation:

r + 3 = 3 ( r - 5 )​

Distribute

r+3 = 3r-15

Subtract r from each side

r+3-r = 3r-r -15

3 = 2r-15

Add 15 to each side

3+15 = 2r-15+15

18 = 2r

Divide each side by 2

18/2 = 2r/2

9 =r
