\(\left(x+x\times2\right):24=305\)
\(3x:24=305\)
\(3x=305\times24\)
\(3x=7320\)
\(x=7320:3\)
\(x=2440\)
Vậy \(x=2440\)
( x+x*2) =305*24
(x+x*2) =7320
x+x*2 = 7320
x*1+x*2 = 7320
x*(1+2) = 7320
x* 3 = 7320
x = 7320:3
x =2440
Nhé
(x+x*2) : 24 =305
=(x+2*x) :24 =305
=3*x : 24 =305
=3*x =305*24=7320
=x =7320:3
=x =2440
