Answer: 
<u>Step-by-step explanation:</u>
P = 2(l + b)
Divide both sides by 2:

Subtract b from both sides:

<em>Note: You can also multiply b by </em>
<em> if you want the left side to be one fraction.</em>

44 - 9 = 35
If we have 44 apples and we take away 9, we have 35 left.
Here's a trick.
Don't solve all the equations, you're given the answer to x so just substitute.
5/2*8+7/2=3/4*8+14
23.5=20 INCORRECT
5/4*8-9=3/2*8-21
1=-9 INCORRECT
5/4*8-2=3/2*8-4 <- YOUR ANSWER
8=8 CORRECT
