Daughter's present age = x. Daughter's age in 30 years time = x + 30.

Carla's present age is y. Carla's age in 30 years time is y + 30.

Use the above to form equations from the statements below:

"Carla is 4 times older than her daugther":

"in 30 years she [the daughter] will be half her [Carla] age":

Solve the equations for x and y. - Oct 12th 2010, 02:38 AManthonye

What about the equation corresponding to

Suppose the daughter's age were 5. How old would Carla be?

Suppose the daughter's age were 10. How old would Carla be?

What did you do? Do the same thing with the x and y mr fantastic used. - Oct 12th 2010, 02:54 AManthonye
