the floor in the back of karl's trunk is 6 ft long and has area of 24 ft^2. Karl wants to haul as many boxes on the floor as pos
sible. He cannot stack the boxes or they will fall out as he drives. If each square box is 2 ft long, how many boxes can karl fit in the back of his truck
If we add the equations it looks like -5y + 8x + 5y + 2x = -18+58 so 10x=40 so x=40/10=4 now let's replace x by 4 in the second equation 5y +2*4=58 5y=58-2*4=58-8=50 so y=50/5=10 so (x, y) = (2, 10)
