Ta có :18 . (x - 16) = 18

  <=>      x - 16  = 18 : 18

 <=>       x - 16  =     1

  <=>      x         = 1 + 16

   <=>     x          =   17

 Vậy S={17}

18 . (x - 16) = 18

        x - 16  = 18 : 18

        x - 16  =     1

        x         = 1 + 16

        x          =   17

18 . (x - 16) = 18

        x - 16  = 18 : 18

        x - 16  = 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

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

=> |x-34|=0:15

=> |x-34|=0

=> 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)

a. |x - 34|.15 = 0

=> |x - 34| = 0

=> x - 34 = 0

=> x = 0 + 34

=> x = 34

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

`@` `\text {Ans}`

`\downarrow`

`x - 32 \div 16 = 18`

`=> x - 2 = 18`

`=> x = 18 + 2`

`=> x = 20`

Vậy, `x = 20.`

`15 + 2x = 17`

`=> 2x = 17 - 15`

`=> 2x = 2`

`=> x = 2 \div 2`

`=> x = 1`

Vậy, `x = 1`

`324 - 13x = 57*5`

`=> 324 - 13x = 285`

`=> 13x = 324 - 285`

`=> 13x = 39`

`=> x = 39 \div 13`

`=> x = 3`

Vậy, `x = 3.`
