That one I can follow.

6/2(x+y) being equal to 3(x+y) I have trouble following.

substituting (1+2) for x in that example is still not the same, as you only have the multiplier.

So you can follow my logic, I was taught 6/2(x+y)
is
6
---
2(x+y)

which is same as

6
---
2x +2y

Sounds like something to send to school with my son, and see what answer his algebra IV professor sends back

EDIT: never mind - I see your reference . almost 5am here.
1/2x = 1/2(x), 6/2x = 6/2(x).

Still curious as to what his prof will say
