5x-11y is the right answer. First you had to used their group like terms, and it gave us, [tex]8x-3x-4y-7y[/tex]. Then you add similar elements, and it gave us, [tex]8x-3x=5x[/tex], or [tex]5x-4y-7y[/tex]. Finally you had to add similar elements again, and it gave us the answer, [tex]-4y-7y=-11y[/tex], or =5x-11y is the right answer. Hope this helps! And thank you for posting your question at here on brainly, and have a great day. -Charlie
