SOLUTION: Solve using Cramers rule: 1. 2x + 5y = 1 3x + 4y = 12 2. x - 5y = 4 -3x + 4y = 4 3. 2x + y - z = -7 x - 4y + 3z = 5 6x

SOLUTION: Solve using Cramers rule: 1. 2x + 5y = 1 3x + 4y = 12 2. x - 5y = 4 -3x + 4y = 4 3. 2x + y - z = -7 x - 4y + 3z = 5 6x - 2y + 5z = 9 Expand by column thr

Question 295483: Solve using Cramers rule:
1. 2x + 5y = 1
3x + 4y = 12
2. x - 5y = 4
-3x + 4y = 4
3. 2x + y - z = -7
x - 4y + 3z = 5
6x - 2y + 5z = 9
Expand by column three:
4. 3 6 1 2
5 9 0 3
-2 -1 0 11
4 -2 0 12

There are other rules that you can find at Rules for asking questions, but do pay particular attention to these:

Daily limit of 4 problems per day. All tutors on algebra.com are FREE.

One problem per submission. Do not dump your whole homework in one question.

If you can, show what you have tried. Tutors like students who try. If a tutor gives you credit for work shown, that problem would not count towards your daily limit.
