The answer would be D... 14 (adults) multiplied by 18 (price for adults) equals 252! 6 (children) multiplied by 12 (price for children) equals 72! 252 + 72 = 324 ღ

Okay. The top equation is the simplest so it would be best to work with that first. The equation is x+y=20. To isolate the x you need to move everything from the left to the right, not including x. To do this you must subtract y from both sides to get x=20-y. From here you plug that into the second equation to get your y coordinate
