First - you need to tell us - what is it that you are supposed to do.

Second: Is your problem

\(\displaystyle \frac{2}{3x} + \frac{2}{3x} = 3\)

or

\(\displaystyle \frac{2}{3}x + \frac{2}{3}x = 3\)

or something else?

Multiply both sides of equation by the denominator (it seems to be the same). Remember, any number divided by itself is 1.

Remember, any number divided by itself is 1. Garf means any number except zero, of course.

MY EDIT: Removed reference to the set of Real numbers (Subhotosh's point well-taken)

Unreal numbers (complex that is) also follow the same rule....

hi I am having alittle trouble with equations I'm stuck here
12-6x=18-7x
12-6x+6x=18-7x+6x
12=18-x

not sure on how to finish the equation

12=18-x

Add x to both sides

Next time, start your own thread :shock:
