=> x = 17 - 14 = 3
Tk mk nha
a)(x-13)*8=184
x-13=184:8
x-13=23
x=23+13
x=36
b)7*(x:7)=833
x:7=833:7=119
x=119*7=833
Chỉ làm thế thôi , làm tiếp
Trả lời :
a, ( x - 13 ) . 8 = 184
=> x - 13 = 184 : 8
x - 13 = 23
x = 23 + 13
x = 36
b, 7 . ( x : 7 ) = 833
=> x : 7 = 833 : 7
x : 7 = 119
x = 119 x 7
x = 833
c, 9 . ( x + 5 ) = 729
=> x + 5 = 729 : 9
x + 5 = 81
x = 81 - 5
x = 76
d, 1200 : 24 - ( 17 - x ) = 36
=> 50 - ( 17 - x ) = 36
=> 17 - x = 50 - 36
17 - x = 14
=> x = 17 - 14
x = 3
Vậy x = ..............( bạn tự đáp số nha!)^_@
a) 1200 : 24 - ( 17 - Y ) = 36
b) 9 x ( Y + 5 ) = 729

Hok tốt
1. Tìm x
1200 : 24 - ( 17 - x ) = 36
9 x ( x +5 ) = 729
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 :
1200 : 24 - ( 17 - x ) = 36 9 x ( x + 5 ) = 729
Bài 1:Tìm x
A) 1200 : 24 - (17 - x ) = 36 B) 9 x ( x + 5 ) = 729
Help me !!!!!!
a) 1200 : 24 - (17-x) = 36
5 - (17-x) = 36
5 -17 + x = 36
x - 12 = 36
x = 48
a) 50-(17-x)=36
(17-x)=50-36
17-x=14
x = 17-14
x = 3
b) (x+5)=729:9
x+5=81
x = 81-5
x = 76
b) \(9\times\left(x+5\right)=729\)
x + 5 = 81
x = 76
Tìm x:
a) 1200 : 24 - ( 17 - x) = 36 b) 9 × ( x + 5 ) = 729
a)50-(17-x)=36
-(17-x)=36-50
-17+x=-14
x=-14+17
x=3
Vậy x=3
b)x+5=729:9
x+5=81
x=81-5
x=76
Vậy x= 76
