Add or subtract the following:
\n" ); document.write( "1) x-7/3 - 4/3 -----> on this I have either -11x/3 or 4x/3
\n" ); document.write( "Ans: x-(10/3)
\n" ); document.write( "-----------------------
\n" ); document.write( "2) 1/x + (x+2)/x --------> on this one I came up with 3x/x
\n" ); document.write( "Ans: (x+3)/x
\n" ); document.write( "------------------------
\n" ); document.write( "3) (4x-3)/(x-7) - (2x+8)/(x-7) --------> here I am not sure but I got 2x-5/x-7
\n" ); document.write( "Ans:[4x-3-2x-8]/)x-7
\n" ); document.write( "=[2x-11]/(x-7)
\n" ); document.write( "----------------------
\n" ); document.write( "4) x^2/x+3 + 9/x+3 -------> here I don't understand how to use the power
\n" ); document.write( "Ans: [x^2+9]/(x+3)
\n" ); document.write( "-----------------------
\n" ); document.write( "
\n" ); document.write( "5) (x^2+2x)/3x - (x^2+5x+6)/3x ------> this one I don't know at all :(
\n" ); document.write( "Ans: [x^2+2x-x^2-5x-6]/3x
\n" ); document.write( "= [-3x-6]/3x
\n" ); document.write( "= [-3(x+2)]/3x
\n" ); document.write( "= [-(x+2)]/x
\n" ); document.write( "======================
