Solve  $a\ -\ b\ +\ c\ +d=\ e$  for c

•  $c\ =\ a\ +\ b\ +\ d\ +\ e$  

•  $c\ =\ e\ -a\ +\ b\ -\ d$  
  

•  $c=e\ -d-b-a$  

•  $c=\frac{\ e\ }{abd}$  

Solve for W: A = LW

• A - L = W

• A + L = W

•  $\frac{A}{W}$  = L
  

•  $\frac{A}{L}$  = W

 $y=\ \frac{z}{x}\ \ solve\ for\ x$  

•  $x\ =\ \frac{y}{z}$  

•  $x\ =\ \frac{z}{y}$  

•  $x\ =\ yz$  

•  $x\ =\ y\ -\ z$
