Step-by-step explanation:
If XY is bisector of angle AXN then: 
Answer:
B. No solutions
Step-by-step explanation:
If you try to simplify it, you get
2x-2x = -5-5 or
0 = -10
Which will not be true for any value of x.
If you would draw the lines y = 2x+5 and y=2x-5, you'd see two parallel lines that never intersect. The intersection would be the solution, but, it never happens.
