The answer is

$a = \frac{11}{7} \\ b = \frac{6}{7}$

Step-by-step explanation:

$\frac{3 + \sqrt{2} }{3 - \sqrt{2} } \times \frac{3 + \sqrt{2} }{3 + \sqrt{2} } \\ = \frac{9 + 3 \sqrt{2} + 3 \sqrt{2} + 2}{9 - 3 \sqrt{2} + 3 \sqrt{2} - 2 } \\ = \frac{11 + 6 \sqrt{2} }{7} \\ = \frac{11}{7} + \frac{6}{7} \sqrt{2} \$

In comparison

Then

$a = \frac{11}{7} \\ b = \frac{6}{7}$

X=20 because you add the 5 to the other five then you move the fraction down then you multiply the 2 by the 10 you got with the 5+5 earlier
