Algebra.Com's Answer #552332 by Lenzky(18)![]() ![]() ![]() You can put this solution on YOUR website! Let x be the first number and 2x be the second. \n" ); document.write( "1/x + 1/2x = 3 \n" ); document.write( "2/2x + 1/2x = 3 \n" ); document.write( "3/2x = 3 multiply both side by 2x \n" ); document.write( "3 = 6x divide by 6 to get the value of x \n" ); document.write( "x = 1/2\r \n" ); document.write( "\n" ); document.write( "CHECKING: \n" ); document.write( "x=1/2 get the reciprocal which is 2 \n" ); document.write( "2x= 2(1/2) \n" ); document.write( "2x= 1 get the reciprocal which is 1/1, you can just use 1 \n" ); document.write( "then add \n" ); document.write( "2+1= 3\r \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " |
