Question 826486
Hallo :)


Let's take Danny's age as n + 4 and his sister as n. You mentioned that the sum of their ages is 36. So, we'll put it in an equation and solve for n.


n + n + 4 = 36
2n + 4 = 36
2n = 36 - 4
2n = 32
{{{(2n)/(2)}}} = {{{(32)/(2)}}}
n = 16 years old


Since Danny is n + 4

Danny = 16 + 4
= 20 years old


There you go! All the best :) x
