10 years ago Mrs.Smith’s age was 17 times her daughter Angela’s age. 6 years later, Mrs.Smith’s age would be 4 years less than three times Angela’s age. Assuming Mrs. Smith’s present age as x years and Angela’s age as y years, frame two linear equations to model this situation.

(x-10) = 17y

(x-4)+4 = 3y

If you solve the 2 equations, this is what you get:

 

x = -15/7 and y = -5/7  [Hmm......Funny ages for mother and daughter !!! ]

yep...I made a mistake...thanx!

 

(x-10) = 17(y-10)

(x-4)+4 = 3(y-4)           Sorry !   But I think the question has an error in it .

 

I question the '17' number   

Let's say it was SUPPOSED to be 7

(x-10) = 7(y-10)

(x-4)+4 = 3(y-4)    then y = 12   x = 24
