Two years ago, Henry weighed 30 lb more than Walter. Since that time, Walter had lost 10 lb, while Henry's weights stayed the same. Their present weight together is 300 lb, find how many pounds each weighs now.

Question

anonymous · Answer

2 years ago: H=W+30.
Now W is 10 less, so replace W with W-10 to get H=(W-10)+30. We know H=300, so solve for W.

anonymous · Answer

wait, sorry their weight together is 300

anonymous · Answer

Oh sorry, I misread the question. So we know W+H=300 and H=(W-10)+30. Can you solve these equations simultaneously?

anonymous · Answer

uh... if i can simplify the terms? one second

anonymous · Answer

w+110 and h=140

anonymous · Answer

Not quite - yours don't add up to 300 :)

H=W+20
W+H=W+W+20=300
2W+20=300
W=140

H=W+20
W=140+20=160
