I just found this in a math book, not part of the assignment, and I'd like to know how 3x+7/x+7 doesn't equal 2x.

mind helping?

thanks!

-A friend in fremont

3x+7/x+7 getting a common denominator of "x"

[ 3x^2 + 7 + 7x ] / x

One of our regulars, hectictar, pointed out to me that this might be :

(3 x + 7) / (x + 7) if so, we have

3

x + 7 [ 3x + 7 ]

3x + 21 ]

________

-14

The result is 3 + [ -14 / ( x + 7) ]

Thanks , hectictar !!!!!
