You can put this solution on YOUR website! Manuel is ten times older than his son, Andrew. In 20 years, Manuel's age will be 4 more than twice Andrew's age. How old was Manuel when Andrew was born??
Let A = age of Andrew now
10A = age of Manuel now
10A -A = age of Manuel when Andrew was born
10A + 20 = 4 + 2(A+20)
8A = 24
A = 3
9A = 27
Manuel was 27 years old when Andrew was born
