Answer:

Multiply both sides by 2

Subtract l from both sides

Divide each side by 3

(2R -l)/3 =w

Step-by-step explanation:

R = (l+3w)/2

Multiply both sides by 2

2R = 2* (l+3w)

2R = l+3w

Subtract l from both sides

2R - l = l-l +3w

2R -l = 3w

Divide each side by 3

(2R-l) /3 = 3w/3

(2R -l)/3 =w

1. Multiply both sides by 2 ----------> 2R = l + 3w

2. Subtract l from both sides ----> 2R - l = 3w

3. Divides both sides by 3 ----> (2R - l) / 3 = w
