li-ke cho mình nha
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
720:[41-(2x-5)]=120
Bài giải
720 / [ 41 - ( 2 * x - 5 ) ] = 120
41 - ( 2 * x - 5 ) = 720 / 120
2 * x - 5 = 41 - 6
2 * x = 35 + 5
x = 40 / 2
x = 20
720:[41-(2X-5)]=120
720:[41-(2X-5)]=120
<=> 41-(2X-5)=6
<=> 2X-5=35
<=> x=20
720 - [ 41 - ( 2x - 5 ) ] = 120
tên sao lộn ngược zậy
phải là công chúa băng giá
41 -(2x-5) = 600
=> 2x-5= -559
=> 2x =-559/5
=> x = -1118/5
720 - [41 - (2x - 5)] = 120
41 - (2x - 5) = 720 - 120
41 - (2x - 5) = 600
2x - 5 = 41 - 600
2x - 5 = - 559
2x = - 559 + 5
2x = - 554
x = - 554 : 2
x = - 277
720:[41-(2x-5)]=120
\(720:\left[41-\left(2x-5\right)\right]=120\)
\(\Rightarrow41-2x+5=6\)
\(\Rightarrow41-2x=1\)
\(\Rightarrow2x=40\)
\(\Rightarrow x=20\)
720 : [ 41 - ( 2x - 5 ) ] = 120
41 - ( 2x - 5 ) = 720 : 120
41 - ( 2x - 5 ) = 6

Học tốt #
720 : [ 41 - ( 2x - 5 )] = 120
[ 41 - ( 2x - 5 )] = 120 x 720
[ 41 - ( 2x - 5 )] = 86400
( 2x - 5 ) = 86400 + 41
( 2x - 5 ) = 86441

Học tốt nhé!
Tìm x biết 720:[41-(2x-5)]=120
=> 41 - ( 2x - 5) = 720 : 160 = 6
=> 2x - 5 = 41 - 6
=> 2x - 5 = 35
=>2x = 40
=> x = 20
Vậy x = 20
Ta co:
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 x bằng 20
720 : [ 41 - ( 2x - 5 ) ] = 120
=> 41 - ( 2x - 5 ) = 720 : 120 = 6
=> 2x - 5 = 41 - 6 = 35
=> 2x = 35 + 5 = 40
=> x = 40 : 2 = 20
đúng nha !!!
\(720:\left[41-\left(2x-5\right)\right]=120\)
\(720:\left[41-\left(2x-5\right)\right]=120\)
\(\Leftrightarrow41-\left(2x-5\right)=6\)
\(\Leftrightarrow2x-5=35\)
\(\Leftrightarrow2x=40\)
\(\Leftrightarrow x=20\)
hok tốt!
720 : [ 41 - ( 2x - 5 ) ] = 120

=>x =40:2
=>x =20
Học tốt !
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 x là 20
