Let N be Nando's age and B be his brother's age.
1.N=3%2AB%2B8 Age relationship now.
2.%28N%2B10%29=2%2A%28B%2B10%29%2B5 Age relationship in ten years.
Use equation 1 to solve equation 2 by substitution
%28N%2B10%29=2%2A%28B%2B10%29%2B5
%283B%2B8%29%2B10=2B%2B20%2B5
3B%2B18=2B%2B25
B=7
Substitute back into equation 1.
N=3B%2B8
N=3%287%29%2B8
N=29
Let's verify
1.N=3%2AB%2B8 Age relationship now.
29=3*7+8
29=29
Good answer
2.%28N%2B10%29=2%2A%28B%2B10%29%2B5 Age relationship in ten years.
29+10=2*(7+10)+5
39=2*17+5
39=39
Good answer.
