solve foy x and y using determinants: ax+by=c
dx-ey=f

You can put this solution on YOUR website!
solve for x and y using determinants:
ax+by=c
dx-ey=f
--------------
Find the coefficent determinant: -ae-bd
------------
To solve for "x", replace the coefficents of x by the constants c and f
Find the x-determinant -ce-fb
---------
Then x = (x-determinant) / (coefficient determinant) --------------
To solve for "y", replace the coefficients of y by the constants c and f
Find the y-determinant af-cd
--------------
To y = (y-determinant) / (coefficient determinant)
