You can put this solution on YOUR website!
A number increased by 2/3 of the number is 35. What is the number?\r
\n" ); document.write( "\n" ); document.write( "Let n = \"the number\"
\n" ); document.write( "n + 2%2F3n = 35
\n" ); document.write( "12%2F3n = 35
\n" ); document.write( "which is\r
\n" ); document.write( "\n" ); document.write( "
\n" ); document.write( "5% = 35
\n" ); document.write( "multiply both sides by 3, gets rid of the fraction
\n" ); document.write( "5n = 3(35)
\n" ); document.write( "5n = 105
\n" ); document.write( "divide both sides by 5
\n" ); document.write( "n = 105%2F5
\n" ); document.write( "n = 21 is the number
\n" ); document.write( ":
\n" ); document.write( "You can check this in the original equation \n" ); document.write( "

\n" );
