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
xl bn, mk lm sai
a) 1200 : 24 - (17-x) = 36
50 - (17-x) = 36
50 -17 + x = 36
33 + x = 36
x = 3
trả lời:
a) = 3
b)= 76
nhớ k thanks nhìu
chúc học tốt
a) 1200 : 24 - ( 17 - x ) = 36
50 - ( 17 - x ) = 36
( 17 - x ) = 50 - 36
17 - x = 14
x = 17 - 14
x = 3
b) 9 . ( x + 5 ) = 729
( x + 5 ) = 729 : 9
x + 5 = 81
x = 81 - 5
x = 76
Chúc bạn học tốt!!! ^_^
A) 1200 : 24 - (17 - x) = 36
50 - (17 - x) = 36
17 - x = 50 - 36 = 14
x =17 -14 = 3
50-(17-x)=36
<=>17-x=14
<=>x=3
