I don’t think you’re wrong good job
I need to see a picture of the question so I can answer the question:)
Answer:

Step-by-step explanation:

<em>Replace it with y</em>

<em>Exchange the values of x and y</em>

<em>Solve for y</em>

<em>Subtracting 1 from both sides</em>

<em>Dividing both sides by 2</em>

<em>Replace it by </em>
So,

X=7
You divide 14 by 2 to find the proportion (7) then multiply it by 1 to get the base length of the large triangle since they’re congruent.
