Let's write the equation exactly the way the problem says, I'll call the \"certain number\" x:
\n" ); document.write( "63 = 6x + 15 subtract 15 from both sides
\n" ); document.write( "48 = 6x flip the equation so we have the unknown on the left:
\n" ); document.write( "6x = 48 divide both sides by 6:
\n" ); document.write( "x = 8
\n" ); document.write( "
\n" );
