1. $\"2x%2B5y=14\"$
\n" ); document.write( "2. $\"x-3y=-4\"$
\n" ); document.write( "Multiply eq. 2 by (-2)
\n" ); document.write( "1. $\"2x%2B5y=14\"$
\n" ); document.write( "2. $\"-2x%2B6y=8\"$
\n" ); document.write( "Then add the two equations and solve for y,
\n" ); document.write( " $\"5y%2B6y=14%2B8\"$
\n" ); document.write( " $\"11y=22\"$
\n" ); document.write( " $\"y=2\"$
\n" ); document.write( "From eq. 1,
\n" ); document.write( "1. $\"2x%2B5y=14\"$
\n" ); document.write( " $\"2x%2B5%282%29=14\"$
\n" ); document.write( " $\"2x%2B10=14\"$
\n" ); document.write( " $\"2x=4\"$
\n" ); document.write( " $\"x=2\"$ \n" ); document.write( "
