Solve using the elimination method:
3x + 2y +z = 14
6x + 2y + 6z = 38
x + 2y + z = 18

x=-2, y=7, and z=6

Step-by-step explanation:

3x + 2y +z = 14

6x + 2y + 6z = 38

x + 2y + z = 18

Take the first and subtract the third.

2x = -4

x = -2

Now the equations become.

2y + z = 20 (both the first and third)

2y + 6z = 50

Subtract the first from the second.

5z=30

z=6

Substitute back.

2y + 6(6) = 50

2y = 14

y=7

the central idea is that:

individuals should refuse to cooperate with institutions they believe unjust.

thoreau felt  that governments were more often agents of corruption than justice, even democracies, and that just because the majority feels a certain way does not make it just or correct in absolute terms. he uses the fact that slavery exists in our democracy to support this idea.

he goes on to say that, as a result, people should live true to their own internal laws regarding right and wrong, as a product of reflection and a moral life, rather than following every law that society imposes. 

step-by-step explanation:

answer: bearing in mind that a rectangle has a perimeter of length + length + width + width.

step-by-step explanation:

p = perimeter

l = length

x=width

p = 2l + 2x

p = 2(l+x)     < ==== perimeter of the base of the box.
