Question

Solve for x (giving double points)

Answer 1

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 2

Answer:

x=-8

Step-by-step explanation:

x+15+x+16=15

=) 2x+31=15

=)2x=15-31

=)2x=-16

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

Hope this helps!
