: : : I am studying for an exam tomorrow and I cannot figure out how to do this problem. The equation is:
: : : x+2=5/3x Any help would be greatly appreciated. Thanks. Tara

: : This is MY way:
: : your equation really is: (x+2) / 1 = 5 / 3x
: : do a criss-cross multiplication (like, if a/b = c/d, then ad = bc):
: : 3x(x + 2) = 5(1)
: : 3x^2 + 6x = 5
: : 3x^2 + 6x - 5 = 0
: : finish it
: In the book it says the answer is 3,but i dunno if thats what you got

If the answer is 3, then the problem must be: x + 2 = (5/3)x

Are you seriously having trouble with it, Tara?

Thanks to your careless typing, Dennis solved a different equation.
Couldn't you tell?
