Respuesta :
for both equations make a similar subject and then put both equations equal to each other....solve for one of the variables and then substitute for then next variable

This question requires that you identify the point of intersection between the two line equations on a common plane. In order to solve, you can either substitute or eliminate. In this case, since neither equation is in the form of x= or y=, we will use elimination. I would suggest eliminating y, since it has the same value in both equations:
(5x + 2y) - (-3x + 2y) = 8x
-4 - 12 = -16
8x = -16
x = -2
Now that we have identified the x value that the equations intersect at, we must find the y value by plugging the found x value into either equation. In this case, I'll use the first equation, but it doesn't really matter:
5(-2) + 2y = -4
-10 + 2y = -4
2y = 6
y = 3
Now we have both the x and y value, and therefore the answer:
(-2, 3).
The answer is A. Hope this helps!
