Algebra.Com's Answer #601119 by Cromlix(4381)![]() ![]() You can put this solution on YOUR website! Hi there, \n" ); document.write( "(x - 7)/x = 48/x + 7 \n" ); document.write( "First sort out denominator \n" ); document.write( "=x(x + 7) \n" ); document.write( "Next cross multiply \n" ); document.write( "(x - 70(x + 7) = (48)(x) \n" ); document.write( "x^2 - 49 = 48x \n" ); document.write( "sort equation into ax^2 + bx + c = 0 form \n" ); document.write( "x^2 - 48x - 49 = 0 \n" ); document.write( "Factorise \n" ); document.write( "(x + 1)(x - 49) = 0 \n" ); document.write( "So, \n" ); document.write( "x + 1 = 0 \n" ); document.write( "x = -1 \n" ); document.write( "or \n" ); document.write( "x - 49 = 0 \n" ); document.write( "x = 49 \n" ); document.write( "Hope this helps:-) \n" ); document.write( " |
