<em />
Looking at the table, we have the following observations.
- <em>The solid column shows indefinite shape (because the particles fill in the container)</em>
- <em>The liquid column is properly cataloged</em>
- <em>The gas column shows a definite shape</em>
<em />
Solid has definite shape, while gas doesn't.
To make corrections, Marcus needs to switch the gas and the solid column.

Answer:
x+y=0 and 3x-2y=10
Step-by-step explanation
Let the numbers be x and y.
The sum of the two numbers is 0
Letting the smaller number be y and the
larger number be x:
twice the smaller number
Also, 3 times the larger number
Now ,twice the smaller number subtracted from 3 times the larger number is 10.
Therefore the equations are
and
