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.

a/ => x - 34 = 0 => x = 34

=> x-34=0

=> x=0+34

=> x=34

b. 18.|x-16|=18

=> |x-16|=18:18

=> |x-16|=1

=> x-16=1       hoặc x-16=-1

=> x=1+16       hoặc x=-1+16

=> x=17           hoặc x=15 ( nếu chưa học số âm thì bỏ trường hợp này)

k mik nhé

(x-34). 15=0

x-34=0:15=0

x=34

18(x-16)=18

x-16=18:18=1

x=1+16=17

\(a,\left(x-34\right)\times15=0\) 

\(x-34=0:15\)

\(x-34=0\)

\(x=0+34\)

\(x=34.\)

\(b,18\times\left(x-16\right)=18\)

\(x-16=18:18\)

\(x-16=1\)

\(x=16+1\)

\(x=17.\)

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

a)x-34=0

x=34

b)x-16=1

x=17

a) x=34

b)x=17

(x-34).15=0

x-34=0

x=34

Vậy x=34

b,18(x-16)=18

x-16=1

x=17

Vậy x=17
