5 . 6 = x . 6 + 6
30 = x. 6 + 6
= > x . 6 = 30 - 6
x . 6 = 24
Vậy x = 24 : 6
x = 4
tích nha!
<=> x.6+6=30
<=>x.6 =30-6=24
<=>x =24:6
<=>x =4
Vậy x=4
\(5\cdot6=x\cdot6+6\)
\(\left(4+1\right)\cdot6=x\cdot6+6\)
\(4\cdot6+6=x\cdot6+6\)
\(\Rightarrow x=4\)
5.6-6 = x.6
( 5.6-6):6=x
( 30-6) : 6 = x
24 : 6 =x
4 = x
^_^
5 . 6 = x . 6 + 6
30 = x . 6 + 6
=> x . 6 + 6 = 30
x . 6 = 30 - 6
x . 6 = 24
x = 24 : 6
x = 4
