Algebra.Com's Answer #222346 by mollukutti(30)![]() ![]() You can put this solution on YOUR website! To make things look easier let us re-write the qs as\r \n" ); document.write( "\n" ); document.write( "(x+5)/5 = (x-4)/4 \n" ); document.write( "or, 4(x+5)=5(x-4) By cross multiplication of the denominators \n" ); document.write( "or, 4x + 20 = 5x -20 \n" ); document.write( "or, 4x - 5x = -20 -20 \n" ); document.write( "or, -x = - 40 \n" ); document.write( "or, x = 40 (elimination of negative signs) \n" ); document.write( " |
