Algebra.Com's Answer #269307 by ankor@dixie-net.com(22740)![]() ![]() You can put this solution on YOUR website! Let x = \"the number\" \n" ); document.write( ": \n" ); document.write( "Write an equation just as it says: \n" ); document.write( "\"one half of a number decreased by two thirds is two less than one fifth \n" ); document.write( " of the number find the number \n" ); document.write( " \n" ); document.write( "If we multiply equation by 30, we can get rid of those annoying fractions, results: \n" ); document.write( "15x - 20 = 6x - 30(2) \n" ); document.write( "15x = 6x - 60 + 20 \n" ); document.write( "15x - 6x = -60 + 20 \n" ); document.write( "9x = -40 \n" ); document.write( "x = \n" ); document.write( "x = -4.44, a rather disappointing number, see if it works in the original equation \n" ); document.write( ": \n" ); document.write( " \n" ); document.write( "-2.22 - .67 = -.89 - 2 \n" ); document.write( "-2.89 = -2.89; so I guess x = -4.44 is the solutions\r \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " |
