(x-34).15=0
(x-34) =0.15
(x-34) =0
x=0+34=34
x=34
18.(x-16)=18
(x-16)=18:18
(x-16)=1
x=1+16
x=17
a) ( x - 34 ) . 15 = 0
x - 34 = 0 : 15
x - 34 = 0
x = 0 + 34
x = 34
Vậy x = 34
b) 18 . ( x - 16 ) = 18
x - 16 =18 : 18
x - 16 = 1
x = 1 + 16
x = 17
Vậy x = 17
18* [ x-16 ] =18
x-16 =18/18
x-16 =1
x =1+16
x =17
ngu de vay ma ko biet , ko biet thi lay vi du ma lam
a) ( x - 34 ) . 15 = 0
=> x - 34 = 0
=> x = 34
b) 18( x - 16 ) = 18
=> x - 16 = 1
=> x = 17
