You can put this solution on YOUR website! Mrs. Santos was 25 years old when her eldest daughter was born. Mrs. Santos' age now is 10 years more than 4 times her daughter's present age. What are their present ages?
-----------------
Present Age DATA:
Let daughter's age be "d"
Then mother's age is "4d+10"
----------------------------------------
Ages when daughter was born.
daughter was "0"
mother was (4d+10)-d = 3d+10
---------------------------------
Equation based on ages when daughter was born:
mother's age = 25
3d+10 = 25
3d = 15
d = 5 (daughter's age at present)
4d+10 = 20+10 = 30 (mother's age at present)
