![\bf X\stackrel{3}{\rule[0.35em]{7em}{0.25pt}}Y\stackrel{11}{\rule[0.35em]{23em}{0.25pt}}Z](https://tex.z-dn.net/?f=%20%5Cbf%20X%5Cstackrel%7B3%7D%7B%5Crule%5B0.35em%5D%7B7em%7D%7B0.25pt%7D%7DY%5Cstackrel%7B11%7D%7B%5Crule%5B0.35em%5D%7B23em%7D%7B0.25pt%7D%7DZ%20)
so the line looks more or less like that, with Y splitting XZ on a 3:11 ratio.
that simply means, that XZ is split on 3+11 pieces, and XY is taking up 3 of those pieces.

Answer:
x=-5
Step-by-step explanation:
7/8 = y/11
so multiply 11 to both sides of the equation
so now its (7*11)/8= y
y=77/8
if decimal then 9.625
hope that helps
