Take the following equations and arrange them into a matrix to be solved by reduced row echelon form

Question

3x+4y-2z=-10

5x+7z=22

6x-2y-6z=12

Answer 1

Hi Kandi W.,

With a large parenthesis around the numbers below the matrix would be:

3 4 -2 -10

5 0 7 22

6 -2 -6 12

Notice in the second equation there is no y-term so a zero is in its place.

I hope this helps, Joe.
