Question

A, (x-13)*8=184

B ,7*(x:7)=833

C,9*(x+5)=729

D, 1200:24-(17-x) =36

Answer 1

a, => x-13 = 184 : 8 = 23

=> x = 23 + 13 = 36

b, => x : 7 = 833 : 7 = 119

=> x = 119 x 7 = 833

c, => x+5 = 729 : 9 = 81

=> x = 81 - 5 = 76

d, => 50 - (17-x) = 36

=> 17-x = 50 - 36 = 14

=> x = 17 - 14 = 3

Tk mk nha

Answer 2

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

Answer 3

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!)^_@
