$\"2y=-5x-22\"$
\n" ); document.write( " $\"5x+-+2y+=+-22\"$ Mult by 7
\n" ); document.write( " $\"35x+-+14y+=+-154\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"-4x%2B7y=9\"$ mult by 2
\n" ); document.write( " $\"-8x+%2B+14y+=+18\"$ \r
\n" ); document.write( "\n" ); document.write( "Now add them
\n" ); document.write( " $\"-8x+%2B+14y+=+18\"$
\n" ); document.write( " $\"35x+-+14y+=+-154\"$
\n" ); document.write( "----------------------
\n" ); document.write( " $\"27x+=+-136\"$
\n" ); document.write( " $\"x++=+-5.03\"$
\n" ); document.write( "Now solve for y and you're there\r
