Answer 1

(72+s-40)-(30-10+5)=50:2
(32+s)-25=25
32+s=25+25
32+s=50
s=50-32
s=18

Answer 2

(8X9+s-5X8)-(30-5X2+5)=100:2:2
                                        =50:2
(8X9+s-5X8)-(30-5X2+5)=25
(72+s-40)-(30-10+5)=25
(72+s-40)-(20+5)=25
(72+s-40)-25=25
72+s-40=25+25
72+s-40=50
72+s=50+40
72+s=90
s=90-72
s=18
