Let <em>A</em> be your age, <em>B</em> be the age of your brother and <em>S</em> be the age of your sister.
Since your brother is 1/4 your age, then:

Since your sister is 8 years older than your brother, then:

Since your sister is 12 years old, then:

Use the second equation to find your brother's age by plugging in <em>S=12</em>:

Plug in <em>B=4</em> in the first equation to find your age:

Therefore, you are 16 years old.
I = {2.666666667, 1.166666667
Let the smaller of the two numbers be x. Therefore the larger number is 1 bigger, x+1.

We can solve this equation for x, which will be one of our two numbers.



Now that we've found x, we can find x + 1. In this case,

.
Therefore, the two numbers are 29 and 30.
