solve this equation using cramer's rule
5x+2y=8
2x-3y=7
---------------
5...2
2...-3
coefficient determinant: 5*-3-2*2 = -19
-----------------
8...2
7...-3
x-determinant: 8*-3-2*7 = -38
---------------------
5...8
2...7
y-determinant: 5*7-8*2 = 19
================================
x = x-det/coef det = 2
y = y-det/coef det = -1
=================================
