You can put this solution on YOUR website!
Solve the 2nd equation for x
\n" ); document.write( " $\"+-x+%2B+3y+=+-1\"$
\n" ); document.write( " $\"-x=-1-3y\"$
\n" ); document.write( " $\"x=1%2B3y\"$
\n" ); document.write( "Plug this into $\"4x-12y=5\"$
\n" ); document.write( " $\"4%281%2B3y%29-12y=5\"$
\n" ); document.write( " $\"4%2B12y-12y=5\"$
\n" ); document.write( " $\"4=5\"$
\n" ); document.write( "Since this equality is not true, there is no solution. If you solved both equations for y, you would see that they are parallel lines that never intersect. \n" ); document.write( "

\n" );
