( x - 3 ) : 5 = 34
x - 3 = 34 x 5
x - 3 = 170
x = 170 + 3
x = 173
( x - 3 ) : 5 = 34
x - 3 = 34 x 5
x - 3 = 170
x =170 + 3
x = 173
( x - 3 ) : 5 = 34
x - 3 = 34 * 5
x - 3 = 170
x = 170 +3
x = 173
( x - 3 ) : 5 = 34
=> x - 5 = 34 x 5 = 170
=> x = 170 + 5
=> x = 175
Mình nhầm :
x = 170 + 3
=. x = 173
\(\text{#Hok tốt!}\)
( x - 3 ) : 5 = 34
x - 3 = 34 x 5
x - 3 = 170
x = 170 + 3
x = 173
Vậy x = 173
( x - 3 ) : 5 = 34
( x - 3 ) = 34 . 5
( x - 3 ) = 170
x = 173
Hok tốt
( x - 3) : 5 = 34
x - 3 = 34 x 5
x - 3 = 170
x = 170 + 3
x =173
hok tốt
=173 nhớ kom nha
