What have you tried? Let's call the age of her mother m (current age) and Amy's age a (current age) Then you know that (now)

And you also know that (in twelve years time) , can you solve this simultaneous equation?

Moving this to maths.

So if Amy's age is a and her mothers age is m, then we know that a is m divided by 3 because Amy's age (a) is a third of her moths age. So , do you understand this?

6. and two positive numbers x and y, where x is the larger of the two numbers, have a difference of one and a product of 72. using algebra and showing your working find the values of x and y Zacken
7. Here is a lovely gcse question my friend sent me a few years ago, and i've never forgot it (and always kept it saved)

Edit: for you to try after of course , so off topic but its too good not to share

Well, if their difference is then we know that . If their product is 72, then we can write: .

Now, remember that , which is the same thing as , so: can be written as , now can you solve this?

yes you have. it is 'irrelevant trash' to my question.. remember this yesterday? and this is not a ****ing homework.. i am just solving questions so what do you mean it is the worst thing i could request?
