How do I use Cramer's rule to solve the system of equations #3x-5y=-31# and #2x+y=1#?
Convert the system of linear equations
into the matrix equation
Let u s now find the necessary determinants
The determinant of the coefficient matrix is
By replacing the first column by the right-hand side,
By replacing the second column by the right-hand side,
By Cramer's Rule,
I hope that this was helpful.
