Let \"+n+\" = number of months that
\n" ); document.write( "they both grow
\n" ); document.write( "Let \"+h+\" = the height of the trees
\n" ); document.write( "----------------
\n" ); document.write( "Equation for 1st tree:
\n" ); document.write( "\"+h+=+2n+%2B+50+\"
\n" ); document.write( "Equation for 2nd tree:
\n" ); document.write( "\"+h+=+1%2An+%2B+59+\"
\n" ); document.write( "-------------------
\n" ); document.write( "Set the heights equal to eachother
\n" ); document.write( "\"+2n+%2B+50+=+n+%2B+59+\"
\n" ); document.write( "\"+n+=+9+\"
\n" ); document.write( "they will be the same height in 9 months
\n" ); document.write( "check:
\n" ); document.write( "\"+h+=+2%2A9+%2B+50+\"
\n" ); document.write( "\"+h+=+68+\" inches
\n" ); document.write( "and
\n" ); document.write( "\"+h+=+1%2A9+%2B+59+\"
\n" ); document.write( "\"+h+=+68+\" inches
\n" ); document.write( "OK\r
