You can put this solution on YOUR website!
%28%0D%0A+matrix%28+2%2C+3%2C+%0D%0A+++1%2C+5%2C%0D%0A+++11%2C+2%2C%0D%0A+++10%2C+25%0D%0A+%29%0D%0A%29
-2R1+R2
--->
%28%0D%0A+matrix%28+2%2C+3%2C+%0D%0A+++1%2C+5%2C%0D%0A+++11%2C+0%2C%0D%0A+++0%2C+3%0D%0A+%29%0D%0A%29

0=3 implies no solution.
You can check this by simple substitution:
x=11-5y
2(11-5y)+10y=25
22-10y+10y=25
22=25 <-- false
