Vậy x=34

b, 18.(x-16)=18

Vậy x=17

a) ( x - 34 ) . 15 = 0

=> x - 34 = 0 => x = 34

b) 18 . ( x - 16 ) = 18

=> x - 16 = 1 => x = 17

\(a.\left(x-34\right).15=0\Leftrightarrow x-34=\frac{0}{15}\Leftrightarrow x=34\)Vậy x là 34.

\(b.18.\left(x-16\right)=18\Leftrightarrow x-16=\frac{18}{18}\Leftrightarrow x=17\)Vậy x là 17.
