You can use Cramer's rule, where you use matrices obtained using the coefficients of the unknowns and the corresponding determinants.

Explanation:

You can use Cramer's rule, where you use matrices obtained using the coefficinets of the unknowns, and the determinants;

Where #A# is the matrix of the coefficients of the unknowns, #A_x# is the same matrix but with the first column substituted with the coefficients of the independent terms (numbers without #x# or #y#) and #A_y# is again the same as #A# but with the second column substituted.

This is better than the previous Video.
