Answer:

18

Explanation:

3(s-5)/4 -3 = 4s- (s-3)/2

open the bracket

3s-15/4-3 =45-s-3/2

3s-15/1=42-s/2

cross multiply

2(3s-15)=42-s

3s-30=42-s

3s+s=42+30

4s=72

s=18

Answer:

s = -45/13

Explanation:

3(s - 5)/4 - 3 = 4s - (s - 3)/2

(3s - 15)/4 - 3 = (8s - s + 3)/2

(3s - 15)/4 - 3 = (8s + 3)/2

3(s - 5)/4 - 3 = 3((8/3)s + 1)/2

3[(s - 5)/4 - 1 ] = 3((8/3)s + 1)/2

(s - 5)/4 - 1 = ((8/3)s + 1)/2

(s - 5)/4 - 4/4 = ((8/3)s + 1)/2

(s - 5 - 4)/4 = ((8/3)s + 1)/2

(s - 9)/4 =((8/3)s + 1)/2

(s - 9) = ((8/3)s + 1)(2)

s - 9 = (16/3)s + 2

s - (16/3)s = 6 + 9

(-13/3)s = 15

s = -45/13
