How do I use matrices to solve the system #2x+3y=4# and #5x+8y=11#?

1 Answer

Answer:

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