Intersect, you mean.
\n" ); document.write( "From eq. 1,
\n" ); document.write( " $\"x=7y-10\"$
\n" ); document.write( "Substitute into eq. 2,
\n" ); document.write( " $\"3%287y-10%29-2y=8\"$
\n" ); document.write( " $\"21y-30-2y=8\"$
\n" ); document.write( " $\"19y=38\"$
\n" ); document.write( " $\"y=2\"$
\n" ); document.write( "Then,
\n" ); document.write( " $\"x=7%282%29-10\"$
\n" ); document.write( " $\"x=14-10\"$
\n" ); document.write( " $\"x=4\"$
