Answer 1

a+34=62
a=62-34
a=28
28+34=62

b-68=19
b=68+19
b=87
87-68=19

28+c=91
c=91-28
c=63
28+63=91

45-d=26
d=45-26
d=19
45-19=26

x-(23+48)=18
x-71=18
x=71+18
x=89
89-(23+48)=18

m+(43-27)=52
m+16=52
m=52-16
m=36
36+(43-27)=52

n-(56-25)=59
n-31=59
n=59+31
n=90
90-(56-25)=59

63-49+f=71
14+f=71
f=71-14
f=57

91-36-g=27
55-g=27
g=55-27
g=28
91-36-28=27

t-(28-9)=16
t-19=16
t=16+19
t=35
35-(28-9)=35

r-37=26
r=26+37
r=63
63-37=26

Answer 2

a+34=62⇒a=62-34=28
b-68=19⇒b=19+68=87
28+c=91⇒c=91-28=63
45-d=26⇒d=45-26⇒d=19
x-(23+48)=18⇒x-71=18⇒x=18+71=89
y-(78-64)=47⇒y-14=47⇒x=47+14=61
m+(43-27)=52⇒m+16=52⇒m=52-16=36
n-(56-25)=59⇒n-31=59⇒n=59+31=90
63-49+f=71⇒14+f=71⇒f=71-14=57
91-36-g=27⇒55-g=27⇒g=55-27=28
t-(28-9)=16⇒t-19=16⇒t=16+19=35
r-37=26⇒r=26+37=63
