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
