solve for x in this expression?
\n" ); document.write( "x+1/x+5=x+2/x+4
\n" ); document.write( ":
\n" ); document.write( "Assume the problem is:
\n" ); document.write( " $\"%28x%2B1%29%2F%28x%2B5%29\"$ = $\"%28x%2B2%29%2F%28x%2B4%29\"$
\n" ); document.write( "Cross multiply and you have:
\n" ); document.write( "(x+5)*(x+2) = (x+1)*(x+4)
\n" ); document.write( "FOIL
\n" ); document.write( "x^2 + 7x + 10 = x^2 + 5x + 4
\n" ); document.write( ":
\n" ); document.write( "Group x's on the left, numbers on the right
\n" ); document.write( "x^2 - x^2 + 7x - 5x = 4 - 10
\n" ); document.write( "2x = -6
\n" ); document.write( "x = $\"%28-6%29%2F2\"$
\n" ); document.write( "x = -3
\n" ); document.write( ";
\n" ); document.write( "Leave it to you to substitute -3 for x in the original problem, and check for equality \n" ); document.write( "

\n" );
