Adelivery truck is transporting boxes of two sizes: large and small. the large boxes weigh 45 pounds each, and the small boxes weigh 35 pounds each. there are 115 boxes in all. if the truck is carrying a total of 4575 pounds in boxes, how many of each type of box is it carrying?

You have effectively wasted 1 hour of my time. Congratulations.

115 = 65 + 50

45(65) + 35(50) = 2925 + 1750 = 4675
45(50) + 35(65) = 2250 + 2275 = 4525

115 = 55 + 60

45(55) + 35(60) = 2475 + 2100 = 4575

Therefore 55 large boxes and 60 small boxes. Absolutely no more of these questions; I got stuck for 40 minutes using trial and error, even though that's the only way you can solve two variables in one equation with integers.

Just divide the x axis (the top) by 2 or multiply the y axis (the bottom) by 2
