Step-by-step explanation:

 \frac{5 -  \sqrt{3} }{2 -  \sqrt{3} }

We rationalize the denominator

 \frac{5 -  \sqrt{3} }{2 -  \sqrt{3} }  \times  \frac{2 +  \sqrt{3} }{2 +  \sqrt{3} }

 =  \frac{(5 -  \sqrt{3}) \times (2 +  \sqrt{3}  )}{(2 -  \sqrt{3} ) \times (2 +  \sqrt{3}) }

 =  \frac{10 + 5 \sqrt{3}   - 2 \sqrt{3}  - 3}{4 - 3}  \:  \:  \:  \: using \: {a}^{2}  -  {b}^{2}  = (a + b)(a - b)

 \frac{7 + 3 \sqrt{3} }{1}  = 7 + 3 \sqrt{3}

After comparing with question

x = 7

y = 3

Hope this helps....
