1. $\"-6x-7y=47\"$
\n" ); document.write( "2. $\"-3x%2B5y-19\"$
\n" ); document.write( "Multiply eq. 2 by ( $\"-1\"$ ) and add the quations together.
\n" ); document.write( " $\"-6x-7y%2B6x-10y=47%2B38\"$
\n" ); document.write( " $\"-17y=85\"$
\n" ); document.write( " $\"highlight%28y=-5%29\"$
\n" ); document.write( "Then use either equation to solve for $\"x\"$ .
\n" ); document.write( " $\"-3x-25=-19\"$
\n" ); document.write( " $\"-3x=6\"$
\n" ); document.write( " $\"highlight%28x=-2%29\"$ \n" ); document.write( "

\n" );
