a/ => x - 34 = 0 => x = 34
b/ => x - 16 = 1 => x = 17
(x-34).15=0
x-34=0
x=34
18(x-16)=18
x-16=1
x=17
a) ( x - 34 ) . 15 = 0
=> x - 34 = 0
=> x = 34
b) 18( x - 16 ) = 18
=> x - 16 = 1
=> x = 17
a ) ( x - 34 ) . 15 = 0
x - 34 = 0 : 15
x - 34 = 0
x = 0 + 34
x = 34
b ) 18 . ( x - 16 ) = 18
x - 16 = 18 : 18
x - 16 = 1
x = 1 + 16
x = 17
a) \(\left(x-34\right).15=0\)
\(\Rightarrow x-34=0\)
\(\Rightarrow x=34\)
b) \(18.\left(x-16\right)=18\)
\(\Rightarrow x-16=1\)
\(\Rightarrow x=17\)
a) (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
