Question

Laila is 14 years older than tom. Laila is 5 years younger than Dan. Altogether they have a combined age of 51. How old are they each?

Answer 1

Laila=l
Tom=t
Dan=d

l=t+14
l=d-5
l+t+d=51

In terms of l:
d=l+5
t=l-14

So:
l+l+5+l-14=51
3l+5-14=51
3l-9=51
3l=60
l=20
d=25
t=6

Hope this helps :)
