tim x: 1200:24[17-x]=36
1200:24x[17-X]=36
50x[17-X]=36
17-X=36:50
17-X=0,72
X=17-0,72
X=16,28.
tìm x
1200:24-(17-x)=36
Ta có : 1200:24-(17-x)=36
=> 50-(17-x)=36
=>17-x=50-36
=>17-x=14
=>x=17-14=3
50 - (17 - x ) = 36
17 - x = 50-36= 14
x = 17 - 14 = 3
Vậy x = 3
1200:24-(17-x)=36
50-(17-x)=36
17-x=50-36
17-x=14
x=17-14
x=3
tìm x
1200:24-(17-x)-36
1200 : 24 -( 17 - x )=36
1200 : 24 -( 17 - x )=36
50 -( 17 - x )=36
17 - x = 50 - 36
17 - x = 14
x = 17 - 14
x = 3
1200 : 24 -( 17 - x )=36
50 -( 17 - x )=36
17 - x = 50 - 36
17 - x = 14
x = 17 - 14
x = 3
x=3 em nhé
chuc em hok tt
a) 1200:24-(17-x)=36
a) 1200:24-(17-x)=36
50-(17-x)=36
17-x=50-36
17-x=14
x=17-14
x=3
**** cho mik nhé ^-^
a) 1200 : 24 - ( 17 - x ) = 36
<=> 50 - ( 17 - x ) = 36
<=> 17 - x = 50 - 36
<=> 17 - x = 14
=> x = 17 - 14
Vậy x = 3
Hok tốt

Tìm x: a) 1200 : 24 - ( 17 - x) = 36
a. 1200: 24 - ( 17 - x) = 36
50 - ( 17- x) = 36
17 - x = 50 - 36
17 - x = 14
x = 17 - 14
x = 3
1200:24-(17-x)=36
1200:24-(17-x)=36
=>50-(17-x)=36
=>17-x = 50-36
=> 17 - x = 14
=> x = 17-14
=> x = 3
1200:24-(17-x)=36 50 -(17-x) =36 17-x = 50-36 (tìm số trừ) 17-x = 14 x = 17 -14 (tìm số trừ) x = 3
1200:24-(17-x)=36 50-(17-x)=36 17-x=50-36(tìm số trừ) 17-x=14 x=17-14(tìm số trừ) x=3
Tính bằng hai cách
24/17 x 28/19 x 5/17 x 11/19
Tìm x :
1200 : 24 - ( 17 - x )2 = 34
1200 : 24 - ( 17 - x )2 = 34
50 - ( 17 - x )2 = 34
( 17 - x )2 = 50 - 34
( 17 - x )2 = 16
( 17 - x )2 = 42
17 - x = 4
x = 17 - 4
x = 13
1200 : 24 - ( 17 - x )2 = 34
50 - ( 17 - x )2 = 34
( 17 - x )2 = 50 - 34
( 17 - x )2 = 16
( 17 - x )2 = 42
=> 17 - x = 4
x = 17 - 4
x = 13
Vậy x = 13
=> 50 - (17-x)^2 = 34
=> (17-x)^2 = 50-34=16
=> 17-x=-4 hoặc 17-x=4
=> x=21 hoặc x=13
