\((x-17)+52=158\)

\(\Rightarrow x-17=158-52\)

\(\Rightarrow x-17=106\)

\(\Rightarrow x=106-17\)

\(\Rightarrow x=89\)

( x- 17 ) + 52 = 158

x - 17 = 158 - 52

x - 17 = 106

x = 106 + 7

x = 113

Vậy x = 113

( x : 23 + 45 ) : 67 = 8911

x : 23 + 45 = 8911 x 67

x : 23 + 45 = 597037

x : 23 = 597037 - 45 

x : 23 = 596992

x = 596992 x 23

x = 13730816

Vậy x = 13730876

(x-17)+52=158

x - 17 = 158 - 52

x - 17 = 106

x= 106+17

x= 123

(x :23 + 45):67=8911

(x : 68 ) : 67 = 8911

x : 68 = 8911 * 67

x : 68 = 597037

x= 597037 x 68

x = 40598516

k mình nhé !!!

a) 135 - ( x + 37 ) = 80

( x + 37 ) = 135 - 80

( x + 37 ) = 55

x = 55 - 37

x = 18

b) ( x - 17 ) + 52 = 158

( x - 17 ) = 158 - 52

( x - 17 ) = 106

x = 106 + 17

x = 123

a) 135 - ( x + 37 ) = 80

x + 37 = 135 - 80

x + 37 = 55

x = 55 - 37

x = 18

b) ( x - 17 ) + 52 = 158

x = 106 + 17

x = 123

a) 135 - ( x + 32 ) = 80

x + 32 = 135 - 80

x + 32 = 55

x = 55 - 32

x = 23

b)( x - 17 ) + 52 = 158

x - 17 = 158 - 52

x - 17 = 106

x = 106 + 17

x = 123

c x : 17 + 83 = 297

x : 17 = 297 - 83

x : 17 = 214

x = 214 x 17 

x = 3638

d) 9052: x - 56  = 17

9052 : x = 17 + 56

9052 : x = 73

x = 9052 : 73

x = \(\frac{1004}{17}\)

a)23

b)123

c)3638

d)1004/17

1/53+-1/106+-1/159=|x|/318

6/318+-3/318+-2/318=|x|/318

1/318=|x|/318

=>|x|=1

x=1 hoặc x=-1

=> \(\frac{1}{53}\)+ \(\frac{-1}{106}\)+\(\frac{-1}{159}\)= \(\frac{\left|x\right|}{318}\)

=> \(\frac{1}{318}\)= \(\frac{\left|x\right|}{318}\)

=> x thuộc {1; -1}

\(\left(1-\frac{52}{53}\right)+\left(\frac{105}{106}-1\right)+\left(\frac{158}{159}-1\right)=\frac{\left|x\right|}{318}\)

\(\Rightarrow\frac{1}{53}+\frac{-1}{106}+\frac{-1}{159}=\frac{\left|x\right|}{318}\)

\(\Rightarrow\frac{1}{318}=\frac{\left|x\right|}{318}\)

\(\Rightarrow\left|x\right|=1\)

\(\Rightarrow x=\pm1\)
