Algebra.Com's Answer #630 by longjonsilver(2297)![]() ![]() You can put this solution on YOUR website! this starts as a fractions question ten finishes as a simple algebra problem.\r \n" ); document.write( "\n" ); document.write( "Fractions...we need to multiply every term (all 3) by the same number, so that the 2, the 3 and 5 in the denominators all cancel with it, so we get rid of the fractions. That number is the lowest common multiple of 2,3 and 5...namely 30!\r \n" ); document.write( "\n" ); document.write( "so, we get \n" ); document.write( "\n" ); document.write( "cancelling, we get \n" ); document.write( "\n" ); document.write( "Hence p = - \n" ); document.write( "\n" ); document.write( "Looking at this, the far simpler solution would be to just combine the 2 fractions on the lefthand side first...\r \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "therefore p = - \n" ); document.write( "\n" ); document.write( "that is much more elegant a solution :-)\r \n" ); document.write( "\n" ); document.write( "cheers \n" ); document.write( "Jon. \n" ); document.write( " |
