Answer 2

are you trying to find what the solutions to x y and z are?

Answer 3

yes

Answer 4

ok so im gonna solve with gaussian's elimination method is that ok?

Answer 5

what ever works for you

Answer 6

Step 1: Multiply first equation by −1 and add the result to the second equation. The result is:
x + y - z = 1
- y + 3z = -1
2x + 2x = 4

Answer 7

Multiply first equation by −2 and add the result to the third equation. The result is:
x + y - z = 1
-y +3z = -1
+2z = 2

Answer 8

Step 3: Solve for z.
2z = 2
z = ?

Step 4: Solve for y.
-y + 3z = -1

Step 5: Solve for x by substituting z and y into the first equation

Answer 9

you got that?
