Solve the following system of equations using Gaussian elimination:(adsbygoogle = window.adsbygoogle || []).push({});

3w+10x-2y+3z=55

w+12x-11y-z= 69

-3w-6x-5y-10z=-47

-3w+9x+5y+4z=-1

Here's what I did so far:

swap R1 and R2 (row 1 and row 2)

-3R1+R2 (multiply row 1 by -3 and add row 2 to that product)

3R1+R3

3R1+R4

Now, after that I think I may have made a mistake because I eventually get some very odd fractions that could not possibly be correct. Can somebody tell me what the steps are???
