The answer is c. I just did the math it is hard to explain how I did it though. Hopefully this helps you! :)
Answer:
Subtract 3 and one-fifth from both sides of the equation
Step-by-step explanation:
Well to find n you gotta separate it.
3 1/5 + n = 9
-3 1/5
n = 5.8
<em>Thus,</em>
<em>to seperate it you subtract 3 1/5 from both sides.</em>
-6x^2+4x
my reasoning:
eliminate the opposites (5 & -5)
collect the like terms (-8x^2 & + 2x^2)
collect the like terms again (-3x &+7x)
Answer: Infinite solutions.
Step-by-step explanation:

Plug the value of y into the second equation.

Add 12 on both sides.

Add 4x on both sides.
