a,(x-34).15=0
x-34 = 0:15
x-34 = 0
x = 0+34
x = 34
------------------------
b,18.(x-16)=18
x-16 = 18:18
x = 1
x = 1+16
x = 17
a)(x-34).15=0
(x-34)=0:15
x-34=0
x=0+34
x=34
b)18.(x-16)=18
x-16=18:18
x-16=1
x=1+16
x=17
li-ke cho mình nha
Tìm số tự nhiên x, biết:
a) (x - 34) . 15 = 0 b) 18 . (x - 16) = 18
a,(x-34).15=0
x-34 = 0:15
x-34 = 0
x = 0+34
x = 34
------------------------
b,18.(x-16)=18
x-16 = 18:18
x = 1
x = 1+16
x = 17
a) ( x - 34 ) . 15 = 0
=> x - 34 = 0
=> x = 34
b) 18( x - 16 ) = 18
=> x - 16 = 1
=> x = 17
