Combining undefined and undefined to get undefined 

Adding 7 to both sides of the equation.

Subtracting 2 from both sides of the equation. 

$$\frac{SA}{h}-2B=P$$

$$\frac{SA-h}{2B}=P$$

$$SA-2B-h=P$$

$$\frac{SA-2B}{h}=P$$

$$b=y-mx$$

$$b=y+mx$$

$$b=my+x$$

$$b=my-x$$

$$L=2P-4W$$  

$$L=\frac{P-2W}{2}$$  

$$L=P-2W$$  

$$L=\frac{P+2W}{2}$$
