we have

x = adult tickets

y = children tickets

and the equations

x + y = 60

11x + 6y = 460

then solve the system:


\begin{gathered} x+y=60 \\ x+y-y=60-y \\ x=60-y \\ \text{then} \\ 11(60-y)+6y=460 \\ 660-11y+6y=460 \\ 660-5y=460 \\ 660-5y-660=460-660 \\ -5y=-200 \\ -(5y)/(-5)=-(200)/(-5) \\ y=40 \end{gathered}

and for x


x=60-40=20

answer: 20 adult tickets and 40 children tickets
