    S=number of students

    a=number of adults

    cost=costadult+costkids

    cost=4a+2s

    cost=360

    360=4a+2s

    total tickets is 105

    105=s+a

    so we got

    our equations are

    4a+2s=360 and

    a+s=105

    so wto solve

    multiply 2nd equation by - 2 and add to first

    4a+2s=360

    -2a-2s=-210 +

    2a+0s=150

    2a=150

    divide by 2

    a=75

    sub back

    s+a=105

    s+75=105

    minus 75 both sides

    s=30

    30 student tickets and 75 adult tickets

    equation 1: 4a+2s=360

    equation 2: a+s=105
