We need to solve the above problem using the method of matrices.

X = 2, Y = 1 .

Arrange the elements of equations in matrices and find the coefficient matrix, variable matrix, and constant matrix. Write the equations in AX=B A X = B form. Take the inverse of A by finding the adjoint and determinant of A . Multiply the inverse of A to matrix B , thereby finding the value of variable matrix X .
