You can put this solution on YOUR website!
x = the number
\n" ); document.write( "3x = three times the number
\n" ); document.write( "x+7 = 7 more than the number
\n" ); document.write( "2x - (-11) = twice the number minus -11 (if that is what you mean?)
\n" ); document.write( ".
\n" ); document.write( "3x + x+7 = 2x - (-11) = 2x+11
\n" ); document.write( "4x + 7 = 2x + 11
\n" ); document.write( "2x = 4
\n" ); document.write( "x = 2
\n" ); document.write( ".
\n" ); document.write( "Checking...
\n" ); document.write( "3x + x+7 = 3(2) + 2+7 = 6+9 = 15
\n" ); document.write( "2x + 11 = 2(2) + 11 = 15
\n" ); document.write( ".
\n" ); document.write( "So, the number is 2.
