+56 Vernon has 2/5 as many stamps as Walsh at first. They then sold the same number of stamps each. Vernon now has 57 stamps which is one-third the number of stamps Walsh have. Find the number of stamps each of them had at first.
+63 Let me express this using algebra. Vernon is V, Walsh is W, and the number of staps sold per person is X.
V= 2/5W which is 5/2V= W
V-X=57
W-X=57*3
Let me bring V= 2/5W into W-X=57*3 first.
5/2V-X=57*3
We can subtract V-X=57 from 5/2V-X=57*3
3/2V=57*3 -57
3/2V=114
V=76
Okay, almost done!
Let's bring V=76 into 5/2V= W
So W= 190 and V=76
Any questions? I hope this helped.
