(1)3x+2y=0
(2)3x+y=2
subtract Equations to cancel out 3x
result:
y=-2
plug in y=-2 into either (1) or (2) to get x = 4/3. Plug x = 4/3 into x- 2z =1
4/3 - 2z=1
4 - 6z = 3
1 = 6 z
answer:
1/6 = z
(2)3x+y=2
subtract Equations to cancel out 3x
result:
y=-2
plug in y=-2 into either (1) or (2) to get x = 4/3. Plug x = 4/3 into x- 2z =1
4/3 - 2z=1
4 - 6z = 3
1 = 6 z
answer:
1/6 = z
