Answer:

hello the system related to your question is missing below is the system

–3x + y – 2z = 10 --------(1)

5x – 2y – 2z = 12 -------- (2)

x – y + z = 23  ----------- (3)

answer :

To reduce the system above to  a 2 * 2 , I would eliminate either Y or Z from the system because a 2 * 2 system requires  X and either Y or Z

Step-by-step explanation:

Given system :

–3x + y – 2z = 10 --------(1)

5x – 2y – 2z = 12 -------- (2)

x – y + z = 23  ----------- (3)

To reduce the system above to  a 2 * 2 , I would eliminate either Y or Z from the system because a 2 * 2 system requires  X and either Y or Z

Eliminating X is not the best way

solving equation 1 and 2

substrate equation (1 ) from equation (2) to eliminate Z

= 8x - 3y = 2

multiply equation (3) by 2 then substrate equation (2) from (3) to eliminate Y

2x - 2y + 2z = 46

-( 5x - 2y - 2z )=  12

= -3x + 4z = 34
