Thank you for the opportunity to help you with your question!

Write tell equations in matching order.

(3x-5y=19) × 2

(7x-2y=-4)× 5

6x-10y=38

35x-10y=-20

Eliminate y by minus sign

-29x=58

X=-2

Y=-5

Please let me know if you need any clarification. I'm always happy to answer your questions.
