Answer:
x = 14
Explanation:
First, organize your work by showing that lines are similar
Line KV is similar to line RV
Line UV is similar to line LV
etc, etc.
=========================================
Now notice that line KV and line RV have the numbers 9 and 18 accordingly
and notice that it's an x2 difference.
==============================================
Now apply the same thing to line UV and LV and divide 26 by 2
That gets us 13
=======================================
Now plug 13 into the equation (2x - 15)
2x - 15 = 13
==========================================
Now solve for X
2x - 15 = 13
Add 15 to each side
2x − 15 + 15 =13 + 15
2x = 28
Divide both sides by 2
2x / 2 = 28 / 2
x = 14
