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

Solve the system of equations: 

• ( 4, 0, -2)
• ( -4, -2, 0)
• None of these
• ( -4, 0, -2)

Solve the system of equations: 

• ( 5, 1, -4)
• (-5, 3, -1)
• None of these
• ( -1, 5, -4)

Solve the system of equations: 

• ( -2, 4, 3)
• ( 2, 1, 6)
• No solution
• None of these

Create a system of equations that matches the picture above.

• x + x + x = 30

  x + y =40

  x + y + z = 100

  z = ?

• x + x + x = 30

  x + y =40

  x + y + 2z = 100

  z = ?

• x + x + x = 30

  2x + y =40

  x + y +2z = 100

  z = ?
