Help with putting these intro matrices and solving?

[janekelly]

I need help on putting these problems into a matrices and solving them. It is really confusing me.
1. 3a-6b=9
2a-3b=7
4b+3c=7

2. Z=-y-1
-x-y+5z=-27
y=-x+7

3. -4x-2y+4z=-22
-3y+z=-17
5x-3y-z=-8

2a-3b=7
4b+3c=7

2. Z=-y-1
-x-y+5z=-27
y=-x+7

3. -4x-2y+4z+-22
-3y+z=-17
5x-3y-z=-8

1.
3a-6b=9
2a-3b=7
4b+3c=7

3a - 6b + 0c = 9
2a - 3b + 0c = 7
0a + 4b + 3c = 7

Now can you put this one matrix form?
