This is the way to solve the problem
Answer:
You can only be able to solve two variables, k and x based on what you input as your question
k= -2x+3
x= (3-k)/2
Answer:
For sure the third one. I think the 1st one too.
Happy learning!
Answer:
No real root.
Complex roots:

Step-by-step explanation:


There are no two integers whose product is 5 and whose sum is 2, so this trinomial is not factorable. We can use the quadratic formula.




Since we have a square root of a negative number, there are no real roots. If you have learned complex numbers, then we can continue.


2x-4y=8
2x=4y+8
x=2y+4
