Lesson 8.2

Systems of Linear Equations in 3 Variables

Fill in the Blank

Determine if  the ordered triple

 $\left(-1,\ -4,\ 5\right)$  is a solution of the system:

 $x-2y+3z=22$ 
 $2x-3y-z=5$  
 $3x+y-5z=-32$  

Fill in the Blank

Solve the system:

 $x+4y-z=20$  

 $3x+2y+z=8$  

 $2x-3y+2z=-16$  

Enter the ordered triple below and submit your work in Showbie -> Notes -> Lesson 8.2 for full credit.
