You can put this solution on YOUR website!
The idea is to isolate the unknown (in this case, 'u') you're interested in to one side of the equal sign -- doesn't matter which side you isolate to.
\n" ); document.write( ".
\n" ); document.write( "5u-w=u+4w
\n" ); document.write( "Subtract u from both sides:
\n" ); document.write( "5u-w-u = u+4w-u
\n" ); document.write( "simplifying:
\n" ); document.write( "4u-w = 4w
\n" ); document.write( "Add w to both sides:
\n" ); document.write( "4u-w+w = 4w+w
\n" ); document.write( "simplifying:
\n" ); document.write( "4u = 5w
\n" ); document.write( "finally, divide both sides by 4:
\n" ); document.write( "4u/4 = 5w/4
\n" ); document.write( "simplifying:
\n" ); document.write( "u = (5/4)w
\n" ); document.write( "or
\n" ); document.write( "u = 1.25w
\n" ); document.write( "
\n" ); document.write( "
\n" );
