x+2y-3z=4
2x+5y+z=2
Here is where i get stuck
we are suppose to do this by using matrix so i set up the matrix:
1 2 -3 | 4
2 5 1 | 2
=>2R1-R2
1 2 -3 | 4
0 -1 -7 | 6
=>R1+R2
1 1 -10 | 10
0 -1 7 | 2
Please help
Thanks
there are only 2 equations given...so how would you make the 3rd equation if you need to?
