X=3
y=5
You have to cancel out either the x values or the y values (I chose y). You multiply both equations by particular numbers so either the x values or y values can be equal to each other, as well as positive or negative to each other. I multiplied -7y by 4 and 4y by 7, and got -28y and 28y. I then canceled those out. The numbers you multiply by also affects the rest of the equations, so I ended up with 48x=4 and -35x=35. After that, you combine like terms, which results in 13x=39. You divide 13 by both sides and you end up with x=3. To find y, all you have to do is plug in the x value to one of the equations, then solve for y. I resulted in y=5.
Hope this helped ^_^
17 spaces. Just jump from each space to the next until you get to (-5,-4). :) hope it helps.
It is the second option, let me know if you got it right
Hey there!
<h3>"Expanded form" is basically, setting it up in a addition form to give you that result</h3>
Good luck on your assignment and enjoy your day!
