Question

720:[41-(2x-5)]=120

 

Answer 1

\(720:\left[41-\left(2x-5\right)\right]=120\)

\(\Rightarrow41-2x+5=6\)

\(\Rightarrow41-2x=1\)

\(\Rightarrow2x=40\)

\(\Rightarrow x=20\)

Answer 2

720 : [ 41 - ( 2x - 5 ) ] = 120

41 - ( 2x - 5 ) = 720 : 120

41 - ( 2x - 5 ) = 6

2x - 5 = 41 - 6

2x - 5 = 35

2x = 35 + 5

2x = 40

x = 40 : 2

x = 20

Answer 3

720 : [ 41 - ( 2x - 5 )] = 120

[ 41 - ( 2x - 5 )] = 120 x 720

[ 41 - ( 2x - 5 )]  = 86400

( 2x - 5 ) = 86400 + 41

( 2x - 5 ) = 86441

2x = 86441 + 5

2x = 86446

x = 86446 : 2 

x = 43223

Answer 4

720 : [41 - (2x - 5)] = 120

41 - (2x - 5) = 720 : 120

41 - (2x - 5) = 6

2x - 5 = 41 - 6

2x - 5 = 35

2x = 35 + 5

2x = 40

x = 40 : 2

x = 20

vậy_

cảm ơn các bạn rất nhiều

Answer 6

=>41-(2x-5)=720:120

=>41-(2x-5)=6

=>2x-5=35

=>2x=40

=>x=20

Answer 7

720:[ 41-( 2X- 50)]= 120.

=> 41-( 2X- 50)= 720: 120.

=> 41-( 2X- 5)= 6.

=> 2X- 5= 41- 6.

=> 2X- 5= 35.

=> 2X= 35+ 5.

=> 2X= 40.

=> X= 40: 2.

=> X= 20.

Vậy X= 20.
