Well, PEMDAS is the most important thing here.
So, do the parentheses first.
[7+w+(-9)] You can take the parentheses around -9 away and make it [7+w-9]. Now, combine the -9 and the 7. So the stuff inside the parentheses becomes [w-2].
Now, go back to the 13[w-2]. You can distribute it in to make it 13w-26.
(: That’s your answer.

we can simplify 7+w+(-9) as w-2
then multiply by 13 as 13w-26

Don’t you need it to equal something, in order to solve for a variable? Idk, thats just what i learned. But, Im not exactly a professional math teacher.
