Answer 1

S) (72+5-40)-(30-10+5)= 50:2
(77-40)-(20+5)= 25
37-25= 25
12=25

T) (36-30-0+72-70=28
6+72-70=28
78-70=28
8=28

U) (49-36)-8-20=9
13-8-20=9
5-20=9
-15=9

V) (v-25-16)+30-50=3
(v-25-16)+30=3+50
(v-25-16)+30=53
v-25-16=53-30
v-25-16=23
v-25=23+16
v-25=39
v=39+25
v=64

X) (x+16+48)-72+64=60+8
(x+16+48)-72+64=68
(x+16+48)-72=68-64
(x+16+48)-72=4
x+16+48=4+72
x+16+48=76
x+16=76-48
x+16=28
x=28-16
x=12

Y) (y+25)-36=20+3
(y+25)-36=23
y+25=23+36
y+25=59
y=59-25
y=34

Z) (54-z)-30+8=12
(54-z)-30=12-8
(54-z)-30=4
54-z=4+30
54-z=34
z=54-34
z=20
