Solving Systems of Equations using Matrices

Solve the system of equations: 

• ( -2, 3, -3)
• None of these
• ( -2, -3, 3)
• ( -3, 3, -2)

Solve the system of equations:
x + y + z = 4
x = -2y
z = -3y

• (2, -1, 3)
• (2, 3, 1)
• None of these
• (4, 1, -1)

• (2, 4, 5)

• (-2,-4, 5)

When solving a system AX=B using inverse matrices, you use the equation:

• X=A^-1B
• B=X^-1A
• A=X^-1B
• X=B^-1A
