19 children tickets and 31 adults ticket were sold
2x+5y = 193
Step-by-step explanation:
sold 19 tickets for children $2 = 19×2 = $38
sold 31 tickets for adult $5 = 31×5 = $155
Total debut = $38 + $155 = $193
Total Seats = 19 (children)+ 31 adults) = 50 seats
2x+ 5y = 193 where x denotes children tickets and y denotes adult tickets
2(19)+5(31) =193
(2×19) + (5×31) = 38 + 155 = 193
