Algebra.Com's Answer #818471 by Theo(13342)![]() ![]() You can put this solution on YOUR website! let x = the denominator. \n" ); document.write( "then 2x - 1 = the numerator. \n" ); document.write( "your fraction is (2x - 1) / x. \n" ); document.write( "add 3 to both numerator and denominator to get: \n" ); document.write( "(2x + 2) / (x + 3) = 3/2 \n" ); document.write( "multiply both sides of the equation by (x + 3) to get:3x \n" ); document.write( "2x + 2 = 3/2 * (x + 3) \n" ); document.write( "multiply both sides of the equation by 2 to get: \n" ); document.write( "4x + 4 = 3 * (x + 3) \n" ); document.write( "simplify to get: \n" ); document.write( "4x + 4 = 3x + 9 \n" ); document.write( "subtract 3x from both sides of the equation and subtract 4 from both sides of the equation to get: \n" ); document.write( "x = 5.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "that should be your solution. \n" ); document.write( "confirm by replacing x in the original equation with 5 to get: \n" ); document.write( "(2x - 1) / x becomes: \n" ); document.write( "9 / 5 \n" ); document.write( "add 3 to both numerator and denominator to get: \n" ); document.write( "12 / 8 \n" ); document.write( "simplify to get: \n" ); document.write( "3/2.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "x = 5 checks out ok. \n" ); document.write( "your solution is that the original fraction is 9/5. \n" ); document.write( " |
