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 !!! ]
