The denominator of a fraction is one less than twice the numerator. If seven is added to both the numerator and the denominator, the resulting fraction has a value of seven-tenths. Find the original fraction.
\n" ); document.write( "-------------------
\n" ); document.write( "Let the numerator be \"x\".
\n" ); document.write( "The the denominator is \"2x-1\".
\n" ); document.write( "------------------------------------
\n" ); document.write( "Equation:
\n" ); document.write( "(x+7/(2x-1+7) = 7/10
\n" ); document.write( "Cross multiply to get:
\n" ); document.write( "10(x+7) = 7(2x+6)
\n" ); document.write( "10x + 70 = 14x+42
\n" ); document.write( "4x = 28
\n" ); document.write( "x = 7
\n" ); document.write( "2x-1 = 13
\n" ); document.write( "---------------------
\n" ); document.write( "The original fraction is 7/13
\n" ); document.write( "===================================
