tìm x
1200:24-(17-x)=36
$\frac{x + 17}{15}$ = $\frac{-24}{36}$
Tìm x
`[ x + 17 ] / 15 = [-24] / 36`
`36 ( x + 17 ) = -24 . 15`
`36 ( x + 17 ) = -360`
`x + 17 = -360 : 36`
`x + 17 = -10`
`x = -10 - 17`
`x = -27`
Vậy `x = -27`

1200:24-(17-x)-36

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

Giúp mk với các bn ơi
1)
1200 : 24 - ( 17 - x ) = 36
50 - ( 17 - x ) = 36
17 - x = 50 - 36
17 - x = 14
x = 17 - 14
x = 3
9 x ( x + 5 ) = 729
x + 5 = 729 : 9
x + 5 = 81
x = 81 - 5
x = 76
1200:24-(17-x)=36 9.(x+5)=729
50 -(17-x)=36 x+5 =729:9
17-x =50-36 x+5 =81
17-x =14 x =81-5
x =17-14 x =76
x =3
Tìm x
A, (x-13)*8=184
B, 7*(x:7)=833
C, 9*(x+5)=729
D, 1200:24-(17-x) =36
a, x-13=184:8
x-13=23
x=23+13
x=36
Vậy x=36
b,x:7=833:7
x:7=119
x=119x7
x=833
Vậy x=833
c, x+5=729:9
x+5=81
x=81-5
x=76
Vậy x=76
d,50-(17-x)=36
17-x=50-36
17-x=14
x=17-14
x=3
Vậy x=3
Hok tốt
Tìm y biết 1200:24-(17-y)=36
1200:24-(17-y)=36
50-17+y=36
33+y=36
y=36-33
y=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
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
