    Answer:

    so let a=adults tickdts and c=children tickets

    7a+4c=68

    sincr it was 14 ppl,

    let a+c=14

    so, system of equations.

    multiply a+c= 14 all by 4 to get

    4a+4c=56 subtract this from the other

    7a+4c=68

    -3a=-12

    a=4

    plug in to either. for a

    4+c=14

    c=10

    plug into other equation to check.

    7(4)+4(10)=68

    28+40=68

    c=children tickets

    7a+4c=68

    sincr it was 14 ppl,

    let a+c=14

    so, system of equations.

    multiply a+c= 14 all by 4 to get
