You need to get L by itself. Keep in mind with equality problems that what you do to one side, you must do to the other.
Let me break it down for you.
P=2L+2W, -2w from both sides.
P-2W=2L, now divide the other side by 2.
1/2P-W=L

P=2L+2W
2L=P-2W
L=P/2-(2W/2)
L=1/2P-W

Answer:

50 berries left over

Step-by-step explanation:

55 berries     1700 berries

--------------- = -------------------

1 jar                   x jars

Using cross products

55x = 1700*1

Divide each side by 55

55x/55 = 1700/55

x = 1700/55

Changing to a mixed number

55 goes into 1700 30 times

30 *55 =16501700-1650 = 50

x = 30 50/55 = 30 10/11

There are 50 berries left over
