Algebra.Com's Answer #133327 by nerdybill(7384)![]() ![]() 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( " |
