Choice A - Octahedron is the answer
What you can do is multiply the whole first equation by 12, so 6x + 26.4y = 108.
then since the coefficients of the x value (the number in front of the x) are the same in both equations, you can subtract the second equation from the first:
6x + 26.4y = 108
-(6x + 0.4y = -22)
26y = 130 divide by 26
y = 5
you can then plug y=5 into one of the equations to solve for x:
0.5x + 2.2(5) = 9
0.5x + 11 = 9 subtract 11 from both sides
0.5x = -2 multiply each side by 2
x = -4
