1. $\"3x%2By=5\"$
\n" ); document.write( "2. $\"2x-2y=-2\"$
\n" ); document.write( "Multiply eq. 1 by 2 and add to eq. 2 to eliminate $\"y\"$
\n" ); document.write( " $\"6x%2B2y%2B2x-2y=10-2\"$
\n" ); document.write( " $\"8x=8\"$
\n" ); document.write( " $\"x=1\"$
\n" ); document.write( "Now use either equation to solve for $\"y\"$
\n" ); document.write( " $\"3x%2By=5\"$
\n" ); document.write( " $\"3%281%29%2By=5\"$
\n" ); document.write( " $\"y=2\"$
\n" ); document.write( " \n" ); document.write( "
