The answer is #w=23#.

Explanation:

First we get all the #w# terms on one side:
#7w + 2 = 3w + 94#
#7w - 3w + 2 = 94#

Then we combine them:
#7w - 3w + 2 = 94#
#4w + 2 = 94#

Then we move the 2 over to the other side:

#4w + 2 = 94#
#4w = 94 -2 #
#4w = 92 #

Finally, divide by 4:
#4w = 92 #
#w = 92/4#
#w=23#
