\n" ); document.write( "n = d + 6\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Substitute the second equation into the first equation.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "5(d + 6) + 10d = 120
\n" ); document.write( "5d + 30 + 10d = 120
\n" ); document.write( "15d = 90
\n" ); document.write( "d = 6\r
