Solve for d
$C\ =\ \pi d$

• $C\ -\ \pi=d$

• $C\ +\ \pi=d$

• $\pi C=d$

• $\frac{C}{\pi}=d$

Solve for h
$V\ =\ lwh$

• $V\ -l-w\ =\ h$

• $V-lw\ =\ h$

• $\frac{V}{lw}=\ h$

• $V-\frac{l}{w}=h$

Solve for x:
 $m\ =\frac{x+y}{2}$ 

•  $\ 2m-y=x$ 

•  $\frac{2m}{y}=x$ 

•  $\frac{m-y}{2}=x$ 

•  $2\left(m-y\right)=x$ 

Solve for y:
5x - y = 16

• -y = 5x + 16
• y = 5x + 16
• x = 5y - 16
• y = 5x - 16

Solve:
12x - 4y = 20  ,  for   y 

• y = 3x - 5
• y = -3x + 5
• y = -3x - 5
• y = 3x + 5

Solve the equation for w.  
^{x = w / a}

• w = a / x
• w = x / a
• w = ax
• x = wa

Solve the equation for d. 
d / t = r

• d = r / t
• d = t / r
• d = rt
• d = r - t

Solve:
C = 2πr, for r

• C/(2π) = r
• C + 2π = r
• C - 2π = r
• 2πC = r

a = b + c   , for  c

• c = a - b
• c = a + b
• c = ab
• c = a / b

Solve for x:

• x = yb - v
• x = by - v
• x = by + v
