You can put this solution on YOUR website!
Set 3n+4 = to each possible solution and then solve for n.
\n" ); document.write( "3n+4=4
\n" ); document.write( "3n+4=5
\n" ); document.write( "3n+4=6
\n" ); document.write( "3n+4=7
\n" ); document.write( "3n+4=8\r
\n" ); document.write( "\n" ); document.write( "solve each one and if it is an integer(...,-2,-1,0,1,2,3,...) then it will work.
\n" ); document.write( "3n+4=4
\n" ); document.write( "3n=0
\n" ); document.write( "n=0 (0 is an integer and therefore (A)4 is a solution
\n" ); document.write( ".
\n" ); document.write( "3n+4=5
\n" ); document.write( "3n=1
\n" ); document.write( "n=1/3 (1/3 is not an integer and therefore (B)5 is NOT a solution.
\n" ); document.write( ".
\n" ); document.write( "continue with the others. There are 2 solutions: A and ?
\n" ); document.write( "
\n" );
