Thank you for the opportunity to help you with your question!

------------------------------------------------------------------------------------------

$\Delta ABC\sim \Delta XYZ$

Therefore, the corresponding sides are all in the same proportion.

$\\ \frac{AB}{XY}=\frac{BC}{YZ}=\frac{AC}{XZ}\\ \\ \frac{12}{y}=\frac{x}{4}=\frac{10}{5}\\ \\ \frac{12}{y}=\frac{x}{4}=2\\$

So

12/y = 2

y = 12/2

y = 6

and

x/4 = 2

x = 4*2

x = 8

ANSWER:  x = 8,  y = 6
