We rewrite the left hand side of the equation as a power(a number to a given exponent.

Recall that;

We apply this property to obtain;

Since the exponents are the same, the bases are also the same.
Therefore 
You can use substitution and solve y-x=2 for y which is y= x+ 2 and plug it into the y of the other equasion and you get x=5 y=7
