    Answer:

    Sedan: 4 passengers

    Minivan: 6 passengers

    Step-by-step explanation:

    We can write the following system of equations:

    \begin{cases}2s+1m=14 \\2s+2m=20\end{cases}, where s represents the number of people a sedan can seat and m represents the number of people a minivan can seat.

    Subtracting the first equation from the second, we have:

    2s+2m-(2s+1m)=20-14,\\\\m=6

    Now plug in m=6 in any of the equations to solve for s:

    2s+1(6)=14, \\2s=8, \\s=4

    Verify that the solution pair (4, 6) works:

    2(4)+1(6)=14\: \checkmark \\2(4)+2(6)=20 \: \checkmark

    Therefore, a sedan can hold 4 passengers and a minivan can hold 6 passengers.
