Answer:
Line n bisects segment XY
The length of segment XY = 6
Step-by-step explanation:
Line n is the segment bisector of segment XY
A bisector is to divide into two equal parts, so;
5x + 8 = 9x + 12
4x = -4
x = -1
Total segment = 5x + 8 + 9x + 12
plug in -1 for x;
-5 + 8 + -9 + 12
XY = 3 + 3
XY = 6
