Question
Given: ΔABC, AB = BC
Perimeter of ΔABC = 50
Perimeter of ΔABD = 40
Find: BD
BD is the altitude and I got 15,
15+20+5=40
20+20+10=50

works for me.
I hope you calculated BD and didn't just guess around till you got a number that worked.

2x+y=50
x+1/2y+(a^2+b^2=c^2)
x=15
x+1/2y+(a^2+b^2=c^2)
x=15

Interesting. I did it like this:
2x+2y = 50, so x+y=25
x+y+h = 40
25+h = 40
h = 15
2x+2y = 50, so x+y=25
x+y+h = 40
25+h = 40
h = 15
