How do i solve writing systems of equations in algebra 1? example of an equation i'm working with: meg paid $26 for 2 books and 2 games. megs sister paid $28 for 4 books and 1 game. each book cost the same amount. how much does a book cost? how much does a game cost?

Let books =x and games =y
2x+2y=26
4x+1y=28

If you solve for x and y, x=5 and y=8

Answer for 2: his profit would be $2.88 explanation: you have to first multiply 72 and 0.12 together to get $8.64 once you do that you know how much money the shopkeeper made from selling the candy bars individually. so you have to do 8.64-5.76=2.88 hope that ; )answer for 3: yeah i’m sorry i have no idea what number 3 is. i’m sorry i couldn’t with that.
