1. $\"12x%2B10y=86\"$
\n" ); document.write( "2. $\"x%2By=8\"$
\n" ); document.write( "Multiply eq. 2 by $\"-12\"$ and add to eq. 1 to eliminate $\"x\"$ ,
\n" ); document.write( " $\"12x%2B10y-12x-12y=86-96\"$
\n" ); document.write( " $\"-2y=-10\"$
\n" ); document.write( " $\"highlight%28y=5%29\"$
\n" ); document.write( "Now use either equation to solve for $\"x\"$ .
\n" ); document.write( " $\"x%2B5=8\"$
\n" ); document.write( " $\"highlight%28x=3%29\"$
\n" ); document.write( " \n" ); document.write( "
