The answer is -8. Just plug in the options for x and add both up to get the full length of the line which is 15

Answer:

x=-8

Step-by-step explanation:

x+15+x+16=15

=) 2x+31=15

=)2x=15-31

=)2x=-16

=)[tex]\frac{2x}{2} =\frac{-16}{2} [/tex] (The 2(s) in [tex]\frac{2x}{2}[/tex] cancel out, leaving x= [tex]\frac{-16}{2}[/tex], or x=-8

Hope this helps!
