Thomas purchased a bundle of 8 feet boards for a home project. The bed of his truck is approximated 70 inches long and 80 inches wide. He cannot drive with his tailgate down, what is the best way for him to put his boards in? Why? Support with mathematics. Include an illustration?

So the first thing we do is to multiply the top equation by 3. the reason i want to do this is i notice there will be a 6y on both equations and can possibly add/subtract them. so we get 6y = -3x + 27. adding that and the second equation we get 6x = 27-15 which is 12. divide by 6 and we get 2. ∴ x = 2. substituting 2 into the first equation we get 2y = -2 + 9 which is 7. divide by 2 and we get 7/2. ∴ y = 7/2, x = 2.

I'm sorry your problems aren't showing up on my end but i'd love to sorry
