He can conclude that the system of equations has no solution since one equation in it always results with false equivalency.
Hope this helps.

I was stuck on the same thing in my class test. I ended up failing but if I get the answers to it I’ll totally send them to you
Answer:
n=-22
Step-by-step explanation:
rewrite the equation as <u>5(n+4)</u><u> </u>= n-8
3
now distribute the 5 through the parentheses <u>5n</u><u>+</u><u>2</u><u>0</u><u> </u>= n-8
3
multiply each side by 3 5n+20=3n - 24
subrtact 3n from both sides 5n+20=3n - 24
-3n -3n
2n+20=-24
then subtract 20 from each side 2n +20=-24
-20 -20
Giving you 2n=-44 then divide both sides by 2
<u>2n</u>=<u>-44</u><u> </u>Giving you n=-22

Answer: C 2x(x - 2) - x = 0
and <u>B</u> 2x² – 5x=0
Step-by-step explanation:
You get 2x(x - 2) - x = 0 by subtracting x from both sides of the original equation.
Then take 2x(x - 2) - x = 0 and distribute to get 2x² - 4x -x = 0
combine the x terma and you end up with 2x² – 5x=0
