1. PhantomCrow

Are you asked to solve for x?

2. PhantomCrow

If this is a proportion, then first cross multiply and then solve for x.$\frac{ x }{ 2}=\frac{ x-4 }{ 3 }$$3x=2(x-4)$$3x=2x-8$

3. anonymous

yeah

4. PhantomCrow

See where you go from there.

5. anonymous

this is the part where i get confused

6. PhantomCrow

Alright. Just use algebra to solve for x from this point$3x=2x-8$$x=-8$

7. PhantomCrow

It's a matter of isolating x via inverse operation.

8. anonymous

where did the 2x go? what did you do to get rid of the 2x

9. PhantomCrow

I subtracted it from both sides. I'm trying to get to equal to something and that wont happen if the x's are on different sides of the equation. Since 2x was positive, I perform the opposite of it (subtraction) to both sides, thus cancelling it on the right and subtracting it from 3x on the left.

10. PhantomCrow

Are you familiar with solving one variable equations?

ohhh I was over thinking it thank you so much !!!

12. PhantomCrow

No problem.
