You can put this solution on YOUR website!
the sum of the numerator and the denominator of a fraction is equal to 7
\n" ); document.write( "n + d = 7
\n" ); document.write( "or
\n" ); document.write( "d = (7-n); use for substitution
\n" ); document.write( ":
\n" ); document.write( "four times the numerator is 8 less than 5 times the denominator
\n" ); document.write( "4n = 5d - 8
\n" ); document.write( ":
\n" ); document.write( "Substitute (7-n) for d in the above equation
\n" ); document.write( "4n = 5(7-n) - 8
\n" ); document.write( "4n = 35 - 5n - 8
\n" ); document.write( "4n + 5n = 35 - 8
\n" ); document.write( "9n = 27
\n" ); document.write( "n = \"27%2F9\"
\n" ); document.write( "n = 3
\n" ); document.write( "then
\n" ); document.write( "d = 7 - 3 = 4:
\n" ); document.write( ":
\n" ); document.write( "\"3%2F4\" is the fraction
\n" ); document.write( ":
\n" ); document.write( ":
\n" ); document.write( "Check solution in the statement,
\n" ); document.write( "\"four times the numerator is 8 less than 5 times the denominator\"
\n" ); document.write( "4(3) = 5(4) - 8\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "
\n" );
