Solve the following system of equations using Gaussian elimination:
3w+10x2y+3z=55 w+12x11yz= 69 3w6x5y10z=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???

I followed your initial steps and finishing the elimination works out just fine despite any fractions. Make sure your arithmetic is correct and don't be afraid of fractions.
