Solve 1/x + 1/(x+5) = 3/4
\n" ); document.write( "-----------
\n" ); document.write( "lcm = 4x(x+5)
\n" ); document.write( "Multiply thru by the lcm to get:
\n" ); document.write( "4(x+5) + 4x = 3(x(x+5))
\n" ); document.write( "4x+20 + 4x = 3x^2 + 15x
\n" ); document.write( "3x^2 + 7x - 20 = 0
\n" ); document.write( "3x^2 + 12x - 5x - 20 = 0
\n" ); document.write( "3x(x+4)-5(x+4) = 0
\n" ); document.write( "(x+4)(3x-5) = 0
\n" ); document.write( "x = -4 or x = 5/3
