Question

60-m=35 x-28=22 100-y=77 37+a=52 b+29=37

Answer 1

$60-m=35 \\ -m=35-60 \\ -m=-25 \\ m=25 \\ \\ x-28=22 \\ x=22+28 \\ x=50 \\ \\ 100-y=77 \\ -y=77-100 \\ -y=-23 \\ y=23 \\ \\ 37+a=52 \\ a=52-37 \\ a=15$

$b+29=37 \\ b=37-29 \\ b=8$

Answer 2

60-m=35                
m=60-35
m=25
x-28=22
x=22+28
x=50
 100-y=77
y=100-77
y=23
 37+a=52
a=52-37
a=15
 b+29=37
b=37-29
b=8
