Question

Solve for x (giving double points)

Answer 1

x=-8

Explanation:

x+15+x+16=15

=) 2x+31=15

=)2x=15-31

=)2x=-16

=)
`(2x)/(2) =(-16)/(2)` (The 2(s) in
`(2x)/(2)` cancel out, leaving x=
`(-16)/(2)`, or x=-8

Hope this helps!

Answer 2

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
