Solving for Variables in Matrices

Write the following system of equations as an augmented matrix.

• 
• 
• 
• 

What is the solution to this system?

• <(2, 3, -1)>

• <(3, -1, 2)>

• <( -1, 3, 2)>

• <(2, -1, 3)>

Solve the system. 

• (5, -6, 3)

• (2, 3, -1)

• (-4, 2, 5)

• No Solution

  z=-1

Solve the system of equations.

• (2, -4, -1)

• (4, -1, -2)

• (-2, 4, 1)

Write the augmented matrix that corresponds to the system

• A

• B

• C

• D

Which of the following is the correct representation for the system of equations?

• A

• B

• C

• D

Jeffrey wrote a matrix to represent his system of equations. What was his mistake

• The z's are not aligned correctly

• There should be a one in the top row for zero

• There should be a zero in the second column of the third representing the y

• Nothing. This is correct.
