Please solve for n. 7/9 = 2n + 1/9

To solve 3n + 4 = 12 first subtract 4 from both sides.

3n=8 then divide both sides by 3

n = 8/3

Do you know jmswilson yourself? I am wondering if there is a reason why you want to prevent him/her learning how to problems like this him/her self.

I don't think fcabanski's intent is to prevent learning. I sometimes create a similar exercise to work out as an example, too.

I read fcabanski's post as a demonstration that there are two steps to solve the OP: (1) isolate the n-term by subtracting the constant from each side and (2) divide each side by the coefficient on n.

Is your teacher aware you're not doing your homework?

:idea: Maybe Wilson is doing their homework, but got stuck on this particular problem for some reason (like arithmetic with fractions, maybe).
