You can put this solution on YOUR website!
$\"+4x+-+12y+=+5+\"$
\n" ); document.write( " $\"+-x+%2B+3y+=+-1+\"$
\n" ); document.write( "solve the second one for x
\n" ); document.write( " $\"+-x+=+-3y+-1+\"$
\n" ); document.write( "multiply through by -1
\n" ); document.write( " $\"+x+=+3y%2B1+\"$
\n" ); document.write( "Substitute this into the first equation
\n" ); document.write( " $\"+4x+-+12y+=+5+\"$
\n" ); document.write( " $\"+4%283y%2B1%29+-+12y+=+5+\"$
\n" ); document.write( "Distribute
\n" ); document.write( " $\"+12y+%2B+4+-+12y+=+5+\"$
\n" ); document.write( "Combine like terms
\n" ); document.write( " $\"+4+=+5+\"$
\n" ); document.write( "This is false so there is NO soulution. In otherwords these two lines are parallel to one another.
