let number of lita stamps = l
and number of adels stamps = a
As per 1st given condition,
l = 2a + 5........(1)
As per 2nd given condition,
l + a = 335
Put the values from (1) and we get;
2a + 5 + a = 335
3a + 5 = 335
subtract 5 from both sides and we get;
3a = 330
divide both sided by 3 and we get;
a = 110
So, number of adels stamps = a = 110
and number of lita stamps = 2a + 5
= 2 * 110 + 5
= 220 + 5
= 225
