Answer:
x = 5.5y - 1
Step-by-step explanation:
this is an equilateral triangle.
(you know that because the sides all have a line through them, meaning they are equal.)
this means that the angles are also equal.
using that, you can make this equation:
7x - 3 = 11y + 5
7x = 11y + 5 - 3
7x - 11y = 2
7x = 11y - 2
x = (11y - 2 )/2
x = 5.5y - 1
I think that's as simplified as it goes..
