292.6 I think
Step-by-step explanation:
to double check just add all sides up together
13(y+3)=13y+39
mutiply the bracket by 13
(13)(y)= 13y
(13)(3)= 39
13y+39= 13y+39
move 13y to the right side
sign changes from +13y to -13y
13y-13y+39= 13y-13y+39
0+39= 0+39
39= 39

-40n = 80
Divide both sides by -40
n = -2
