@GoldPhenoix i think you might be leading him in the wrong direction

goldphenoix · Answer

I want to see his mistake first. :)
So I can help him fix his mistake.

goldphenoix · Answer

This is how you find x, you want to multiply 3 and 2. Why? Well because it would be easier to find x, and it's possible.
So 3*2 = 6.
So your equation should look like: $$\large \large x + 4 = 6$$
Make sense?

anonymous · Answer

so its 2

goldphenoix · Answer

Yes. X is equal to 2. How to make sure if it's 2?
Well plug it in.$$\large \large \frac{ 2+4 }{ 3 } =2$$ The numerator becomes 6.
6/3 = 2.
Yes, x = 2. (Once again)
I hope this help!

When you have an equation with fraction, and you want to solve for x. You want to multiply the base by the denominator. Alright?
