Answer:
![y = 2 \\ {0 \: and \:2}](https://tex.z-dn.net/?f=y%20%3D%20%202%20%20%5C%5C%20%7B0%20%5C%3A%20and%20%5C%3A2%7D)
Step-by-step explanation:
-2 + 2(3) =-2 +6 = 4 for the 2nd equation
2(-2) + 4(3) = -4 +12 = 8 for the 2nd equation
(-2,3) satisfies both equations
let x = 0, then y= 2 (0,2) is another solution
there's multiple solutions, including (-2,3) and (0,2). That eliminates all answers except the first
Try graphing the two equations. They're the same line, with an infinite number of points on the line, which means an infinite number of solutions.
