\n" ); document.write( " $\"B=A%2B120\"$
\n" ); document.write( "Substitute eq. 2 into eq. 1,
\n" ); document.write( " $\"A%2BA%2B120=210\"$
\n" ); document.write( " $\"2A=90\"$
\n" ); document.write( " $\"highlight%28A=45%29\"$
\n" ); document.write( "Then
\n" ); document.write( " $\"B=45%2B120\"$
\n" ); document.write( " $\"highlight%28B=165%29\"$ \n" ); document.write( "
