Emilia Hale · Answer 1

First 7w=L and w=1/7L

so substituting each one respectively we get

16w

16/7L

Keira Stevenson · Answer 2

One way is 16m

To get that you simply add the terms together:

7m + 7m + m + m = 16m

Another way is m (14 + 2)

This one if the factorized form

You have to expand it

14m + 2m = 16
