\(\left(x+x\times2\right):24=305\)
\(\left(x\times1+x\times2\right):24=305\)
\(\left[x\times\left(1+2\right)\right]:24=305\)
\(\left(x\times3\right)=305\times24\)
\(\left(x\times3\right)=7320\)
\(x=7320:3\)
\(x=2440\)
Vậy \(x=2440\)
\(\left(x+x\times2\right):24=305\)
\(\left(x\times1+x\times2\right):24=305\)
\(x\times\left(1+2\right)=305\times24\)
\(x\times3=7320\)
\(x=7320:3\)
\(x=2440\)
Vậy \(x=2440\)
