\(\left(x-34\right)\cdot15=0\)
\(\Leftrightarrow x-34=0\)
\(\Leftrightarrow x=34\)
a)\(\left(x-34\right).15=0\Leftrightarrow x-34=0\Leftrightarrow x=34\)
b)\(18\left(x-16\right)=18\Leftrightarrow x-16=1\Leftrightarrow x=17\)
\(18\left(x-16\right)=18\)
\(\Leftrightarrow x-16=1\)
\(\Leftrightarrow x=17\)
(x-34).15=0
x-34=0
x=0+34
x=34

(x-34).15=0

18(x-16)=18
x-16=1
x=1+16
x=17
18(x-16)=18
x-16=1
x=1+16
x=17
\((x-34)\cdot15=0\)
\(\Leftrightarrow x-34=0\Leftrightarrow x=34\)
\(18\cdot(x-16)=18\)
\(\Leftrightarrow x-16=18:18\)
\(\Leftrightarrow x-16=1\)
\(\Leftrightarrow x=17\)
Vậy x = 34 , x = 17
(x - 34 ) * 15 =0
x - 34 =0
x= 0 + 34
x=34
