Let x= first number
\n" ); document.write( "2x-9=second number
\n" ); document.write( "3x+6=third number so if we add these terms together
\n" ); document.write( "x+2x-9+3x+6=123
\n" ); document.write( "6x-3=123 add 3 to both sides
\n" ); document.write( "6x=126 divide both sides by 6
\n" ); document.write( "x=21
\n" ); document.write( "2x-9=33
\n" ); document.write( "3x+6=69
\n" ); document.write( "21+33+69=123 correct
\n" ); document.write( "Pete
