1. $\"3x-8y=-23\"$
\n" ); document.write( "2. $\"++9x%2B2y=-19\"$
\n" ); document.write( "Multiply eq. 1 by (-3) and add to eq. 2,
\n" ); document.write( " $\"-9x%2B24y%2B9x%2B2y=69-19\"$
\n" ); document.write( " $\"26y=50\"$
\n" ); document.write( " $\"y=50%2F26\"$
\n" ); document.write( " $\"highlight%28y=25%2F13%29\"$
\n" ); document.write( "Use eiither equation to solve for $\"y\"$
\n" ); document.write( " $\"9x%2B2%2825%2F13%29=-19\"$
\n" ); document.write( " $\"9x=-247%2F13-50%2F13\"$
\n" ); document.write( " $\"9x=-297%2F13\"$
\n" ); document.write( " $\"highlight%28x=-33%2F13%29\"$
\n" ); document.write( " \n" ); document.write( "
