Answer:
1.75 tons, one ton is 2000 pounds, and there are 1500 pounds left which is .75 of a ton. Hope this helps!
Use proportions:
(7x-4)/31 = (4y+8)/24 = (y+2)/6
Multiply:
6*(7x-4) = 31*(y+2)---> 42x-24 = 31y+62 ---> 11y = 86, y = 86/11
I don;t like that is looks 'ugly', instead of sth like y = 88/11=8. I think 86/11 is the answer. Check the math! :)
