Help Pleaseee ASAP Solve this linear system:

3x + 4y − z = −6
5x + 8y + 2z = 2
−x + y + z = 0

this image just confuses me, wish i could help

Step-by-step explanation:

Part 1

|A| = -23

|Ax| = -46

|Ay| = 46

|Az| = -92

Part 2

X = 2

Y = -2

Z = 4

Step-by-step explanation:

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116

i don't know, but that looks pretty bad. my school passed us unless we failed in all the subjects, but idk abt ur school's rules.
