\(\left(x-52\right)-62=52\)

\(\Rightarrow x-52=52+62\)

\(\Rightarrow x-52=114\)

\(\Rightarrow x=114+52\)

\(\Rightarrow x=166\)

\(\left(x-52\right)-62=52\)

\(x-52=52+62\)

\(x-52=114\)

\(x=114+52\)

\(x=166\)

Vậy \(x=166\)

#Ayumu

y x 62 - y x 52 = 420

y x (62 - 52) = 420

y x 10 =420

y = 420: 10

y = 42

y *  62 - y * 52 = 420

=>y*(62-52)=420

=>y*10=420

=>y=420:10

=>y=42

42 nhe 

X x 62 - X x 52 = 420

X x ( 62 - 52 )   = 420

X x 10 = 420

       X = 420 : 10

       X = 42

X x 62 -X x52=420

X x (62-52)=420

X x10=420

=>x=42

k đúng ch0 mình nha mấy bạn

10x=420

x=42

x + 24 = 76

x         = 76 - 24

x          = 52

x + 38 = 59

x          = 59 - 38

x           = 21

x + 62 = 84

x         = 84 - 62

x          = 22

x + 22 = 87

x          = 87 -22

x          = 65

x + 14 = 25

x+ 52 = 78

x        = 78 - 52

x        = 26

x + 71 = 94

x         = 94 - 71

x         =23

x + 82 = 86

x          = 86 - 82

x          = 4

a: x+24=76

nên x=52

b: x+38=59

nên x=21

c: x+62=84

nên x=22

d: x+22=87

nên x=65

???????????????????????????

nope :v
