# y=5 #

First simply all like-terms.
# 13y -16 = -81 # (add # 7y # and # 6y #)

Next, you need to isolate the variable, # y #. You can do this by adding # 16 # to both sides.

# 13y - 16 + 16 = -81 + 16 #

When you simply, you get:

# 13y = 65 #

Now you divide both sides by # 13 # to isolate the y.

# (13y)/13 = 65/13 #

When you simply you get:

# y = 5 #
