We can use elimination to solve the system:
x+2y=0 Multiply the first equation by negative 2 so we can eliminate
2x+4y=0
-2-4y=0 Add them, -2X+2X= 0, -4Y+4Y= 0
2x+4y=0
0=0
Since 0 is indeed equal to 0 you have INFINITELY MANY SOLUTIONS.
you could also put both equation in slope intercept form and see if the slopes and Y-intercept are the same.

Step-by-step explanation:
6/36=1/6
Answer:
missing side: 9x -3
Explanation:
length + width + height = perimeter
4x + 1 + 2x - 4 + height = 15x - 6
6x - 3 + height = 15x - 6
height = 15x - 6 - 6x + 3
height = 9x -3
