1. $\"4x-3y=3\"$
\n" ); document.write( "2. $\"2x%2B5y=21\"$
\n" ); document.write( "Multiply eq. 2 by -2 and add to eq. 1,
\n" ); document.write( " $\"4x-3y-4x-10y=3-42\"$
\n" ); document.write( " $\"-13y=-39\"$
\n" ); document.write( " $\"highlight_green%28+y=3%29\"$
\n" ); document.write( "Then use either equation to solve for x,
\n" ); document.write( " $\"2x%2B5y=21\"$
\n" ); document.write( " $\"2x%2B15=21\"$
\n" ); document.write( " $\"2x=6\"$
\n" ); document.write( " $\"highlight_green%28+x=3%29\"$ \n" ); document.write( "

\n" );
