\(a,\left(x-34\right).15=0\)
=>\(x-34=0\)
=>\(x=34\)
Vậy...
b,\(18.\left(x-16\right)=18\)
=>\(x-16=1\)
=>\(x=17\)
Vậy...
1.
a) ( x- 34 ) . 15 = 0
x - 34 = 0:15
x -34 = 0
x=34
b) 18 . ( x -16 ) = 18
x-16 = 1
x = 17
1.
a ) ( x - 34 ) . 15 = 0 b) 18 . ( x - 16 ) = 18
x - 34 = 0 : 15 x - 16 = 18 : 18
x - 34 = 0 x - 16 = 1
x = 0 + 34 x = 1 + 16
x = 34 x = 17
