The reciprocal of twice an integer added to the reciprocal of two more than twice the integer is 7/24.
\n" ); document.write( " What is the integer?
\n" ); document.write( ":
\n" ); document.write( "Let x = the integer
\n" ); document.write( "\"1%2F%282x%29\" + \"1%2F%28%282x%2B2%29%29\" = \"7%2F24\"
\n" ); document.write( "multiply equation by 24x(2x+2)
\n" ); document.write( "24x(2x+2)*\"1%2F%282x%29\" + 24x(2x+2)*\"1%2F%28%282x%2B2%29%29\" = 24x(2x+2)*\"7%2F24\"
\n" ); document.write( "cancel the denominators, results:
\n" ); document.write( "12(2x+2) + 24x = 7x(2x+2)
\n" ); document.write( ":
\n" ); document.write( "24x + 24 + 24x = 14x^2 + 14x
\n" ); document.write( ":
\n" ); document.write( "48x + 24 = 14x^2 + 14x
\n" ); document.write( ":
\n" ); document.write( "Combine on the right
\n" ); document.write( "0 = 14x^2 + 14x - 48x - 24
\n" ); document.write( ":
\n" ); document.write( "A quadratic equation
\n" ); document.write( "14x^2 - 34x - 24 = 0
\n" ); document.write( ":
\n" ); document.write( "simplify, divide by 2
\n" ); document.write( "7x^2 - 17x - 12 = 0
\n" ); document.write( ":
\n" ); document.write( "factor this to
\n" ); document.write( "(7x+4)(x-3) = 0
\n" ); document.write( ":
\n" ); document.write( "The positive solution is all we want here
\n" ); document.write( "x = 3 is the integer, that everyone is waiting for!
\n" ); document.write( ":
\n" ); document.write( ":
\n" ); document.write( "See if this is true
\n" ); document.write( "\"1%2F%282%2A3%29\" + \"1%2F%28%282%283%29%2B2%29%29\" = \"7%2F24\"

\n" ); document.write( "\"4%2F24\" + \"3%2F24\" = \"7%2F24\"
