: : 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
