y=5x\r
\n" ); document.write( "\n" ); document.write( "after 15 years\r
\n" ); document.write( "\n" ); document.write( "y+15=3(x+15)\r
\n" ); document.write( "\n" ); document.write( "y+15=3x+45\r
\n" ); document.write( "\n" ); document.write( "y= 3x+45-15
\n" ); document.write( "y=3x+30\r
\n" ); document.write( "\n" ); document.write( "substitute y=5x\r
\n" ); document.write( "\n" ); document.write( "5x=3x+30
\n" ); document.write( "2x=30
\n" ); document.write( "/2
\n" ); document.write( "x=15\r
