What I've done so far: 5(2x – y = 2) > 10x  5y = 10 (–x + 5y = 3) > x + 5y = 3 Cross out the 5y's.... 10x = 10 x = 3 then I add so 9x/9 = 13/9

so x=13/9 apply this value in ur first eqn and find the value of y.

Write a system of equations to solve the following problem. Let c be the number of child tickets and a be the number of adult tickets. Each child ticket for a ride costs $3, while each adult ticket costs $5. If the ride collected a total of $115, and 33 tickets were sold, how many of each type of ticket were sold? My answer: 3c + 5a = 115 a + c = 33
