\(\Leftrightarrow x-34=0\)

\(\Leftrightarrow x=34\)

Answer 2

a)\(\left(x-34\right).15=0\Leftrightarrow x-34=0\Leftrightarrow x=34\)

b)\(18\left(x-16\right)=18\Leftrightarrow x-16=1\Leftrightarrow x=17\)

Answer 3

\(18\left(x-16\right)=18\)

\(\Leftrightarrow x-16=1\)

\(\Leftrightarrow x=17\)

Answer 4

Answer 5

(x-34).15=0

x-34=0

x=0+34

x=34

hc tốt

Answer 6

18(x-16)=18

x-16=1

x=1+16

x=17

Answer 7

18(x-16)=18

x-16=1

x=1+16

x=17

Answer 8

\((x-34)\cdot15=0\)

\(\Leftrightarrow x-34=0\Leftrightarrow x=34\)

\(18\cdot(x-16)=18\)

\(\Leftrightarrow x-16=18:18\)

\(\Leftrightarrow x-16=1\)

\(\Leftrightarrow x=17\)

Vậy x = 34 , x = 17

Answer 9

(x - 34 ) * 15 =0

x - 34 =0

x= 0 + 34

x=34
