Yes.

For example if we know the lengths of 2 adjacent sides and the measure of the included angle we can find the length of the other side.

That's true; the Law of Cosines works with all triangles. With right triangles it simplifies to the Pythagorean Theorem.

-7 x - 2y = -13 x - 2y = 11

Well the first one would convert to
-2y= 7x-13 and the second one would be -2y=-x+11 and you solve from there (lmk if you need the steps) but your final answer would be. Y= -7/2x+ 13/2 and y=1/2x - 11/2
