3x-2y=7 
2x+7y=38

First find the determinant D of the coefficient matrix.
|3    -2|
|2      7|
Find D

Then replace the x column with the constants and find determinant DX.
|7   -2|
|38   7|
Find DX

Then replace the y column with the constants and find determinant DY.
|3    7|
|2   38|
Find DY

The solution is x = DX/D  and y = DY/D
