Divide the numerator by the denominator and any remaining values go back above the denominator.
Example:
17 / 4 is an improper fraction. To turn it into a proper fraction we do 17 divided by 4.
17 / 4 is 4 with a remainder of 4. So we put the 4 on the outside and the 1 back above the denominator, which is 4.
It ends up looking like this:
Answer:

Step-by-step explanation:
First of all, let's rewrite the first one after dividing both sides by 2.

Now, let's pick one you want to eliminate.
<u>Eliminating x:</u> Let's multiply the first one by 4, the second by 3, and subtract one from the other. Rest is simply solving an equation in one variable

<u>Eliminating y:</u> Let's multiply the first by 5, the second by 2, and add them together. Rest is simply solving an equation in one variable
