Question

I need help with 13. Thank you

Answer 1

Answer:
`y =5 , x=4`

Explanation:

You multiply the bottom equation by 5 so you can cancel the x terms. After that, you add 30y + 6y to get 36y. Next, you add 50 + 130 to get 180. Divide both sides by 36 and you get your first answer of y = 5. Then you plug that into the next equation. Subtract both sides by 30. and divide by a negative one you get your second answer of x=4.

I hope this helps!
