Age Problem :
 Mr. Belen is 30 years older than his son, how old are the father and the son if Mr. Belen is 10 more than thrice as old as his son ?

-pls, answer this problem with a solution ..

thank you ! :)



Sagot :

let 'x' be the age of the son
    'y' be the age of the father(Mr. Belen)
since Mr. Belen is 30 yrs older than his son then,
y = x + 30    ----equation 1
and given that Mr. Belen is 10 more than thrice as old as his son then,
y = 3x + 10  ---equation 2
equate 1 and 2
3x + 10 = x + 30
3x - x = 30 - 10 
2x = 20
x = 10
substitute to equation 1
y = x + 30
y = 10 + 30
y = 40
therefore Mr. Belen is 40yrs old while his son is 10yrs old.
