Convert the given matrix to a system of equations. HELP ME PLEASE!! I'M SO CONFUSED!!

Question



 (Eq₁) 

        

  

(Eq₂) 

        

 

(Eq₃) 

Answer 1

Hello again Lucy!

Remember that each roll in the matrix corresponds to one variable, the first one is x, the second is y and the third is z.

Also remember that each number in the augmented matrix corresponds to the coefficient of the variables.

 (Eq₁)  2x - 3y + z = 5

        

  

(Eq₂) -x + 4y + 8z = 13

        

 

(Eq₃) 6y - 2z = 9

Note that in Eq 3 x is not present because it has coefficient zero.
