solve x+y = 2 ; 2y-z = 0 ; -x-y+z = -1 using cramer's rule (using determinants)
----------------------------------------------

-----------------------------------------------
evaluate the determinant of the coefficient matrix
replace the first column in the above determinant with the vector on the RHS of the equations
take the ratioof the second determinant to the first one to get x
for y replace the second column in the coefficient matrix  and proceed as above ...
