Question 990574
 seven years after her son is born a mother is five times as old as he is. how old was the mother when her baby was born 
-----
baby born:: mother is k yrs old
7 years pass
baby is 7:: Mother is 5*7 = 35:: Mother is also k+7 yrs old
====
Equation::
k+7 = 35
k = 28 yrs (Mother's age when baby was born)
