I just did it btw
Answer:
7/2=3.5 each of them got 3 and half
It's A. y=5 because y-lines are horizontal, and x-lines are vet=rtical, and all horizontal and vertical lines are perpendicular (they create a right angle). y=5 line crosses all points that are (x,5) because the 5 in (x,5) is 5 up from the origin and x left or right. y=5 is a horizontal line that is 5 up from the origin.
Multiply the first equation by 2
-6x + 4y = -78
5x + 4y = 21
Subtract those two equations
-11x = -99
X = 9
Plug in 9 for x in one of the equation
-3(9) + 2y = -39
-27 + 2y = -39
2y = -12
Y = -6
In conclusion, x = 9, y = -6
