The school store is running a promotion on school supplies. Different supplies are placed on two shelves. You can purchase 5 items from shelf A and 2 items from shelf B for $22. Or you can purchase 2 items from shelf A and 5 items from shelf B for $34. Write a system of equations that can be used to find the individual prices for the supplies on shelf A and on shelf B. ​

its 4 because 2 times 2 is 4, if you double the number two you get four

there are 70 more legs than eyes at the dog show (196 – 126 = 70). dogs have two more legs than eyes, and humans have the same number of legs as eyes. thus 70 is twice the number of dogs at the show, so the number of dogs is half of 70, which is 35. to get the number of humans, subtract 35 from 63: 63 – 35 = 28.
