. Solve system of linear equations, using matrix method. x - y + 2z = 7 3x + 4y - 5z = -5 2x - y + 3z = 12

Hello student,
Please find the answer to your question below
writing given equations in the form of matrix we get
AX=B


on solving we get x=2,y=1 and z=3
Hence the system of equations is consistent and has a unique solution
