Answer:
Surprising
Explanation:
This is surprising because the total number of planets in our solar system are nine which revolve around a central star i.e sun in different orbital paths.
Also, out of 9 nearly four planets i.e Mercury, Earth, Venus and Mars are terrestrial i.e having some land forms. Out of remaining 5 non terrestrial planets nearly four planets are gas planets (Jupiter, Uranus, Neptune and Saturn) and these planets are distantly positioned from the central star
Hence, the given discovery is surprising

Answer:
x=6/7, y=-228/35
Explanation:
-4x+5y = -36 /*3
15x-3y = 32 /*5
------------------------- here we multiply both equations to get common y
-12x+15y = -108
75x-15y = 160
------------------------- then we add these two equations to eliminate the y
-12x+75x+15y-15y = 54
63x = 54
------------------------- then we get the x
x = 54/63
x = 6/7 (after we divide both with 9)
------------------------ next up, we add the value of x in first equation
-4 * 6/7 + 5y = -36
-24/7 + 5y = -36
------------------------ we leave 5y on the left side
5y = -36 + 24/7
5y = -252/7 + 24/7
-------------------------- common divider is 7 so we multiply 36*7=252
5y = -228/7
y= -228/7/5/1
------------------------- now we leave only y on the left side
y = -228*1/7*5
y = -228/35
------------------------- when dividing the fragment we multiply outer and inner
