Step-by-step explanation:
Keywords
system; linear equations; graphing; solution
we have
-------> equation A
----> equation B
The <u>system</u> of <u>linear equations</u> is composed of equation A and equation B
Substitute the equation B in equation A
Find the value of x
![x=4-2[17/4]=-4.5](https://tex.z-dn.net/?f=x%3D4-2%5B17%2F4%5D%3D-4.5)
The<u> solution</u> is the point 
Using a <u>graphing</u> tool
see the attached figure
therefore
the answer is the option A

The difference between them is 10
-4 - 6 = -10, however since it is only asking for the <em>difference, </em>your answer would be 10.
