Solving Literal Equations

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

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

Solve the equation for x. 
y = x / w

• x = w / y
• w = xy
• x = wy
• y = x / w

Solve the equation for d. 
d / t = r

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

Solve for x.
9y = x / 2w 

• 2y = x / 9w
• x = 18wy
• x = 92yw
• x = 2y - 9w

S = 3F - 24  Solve for F

• F = (S + 24)/3
• F = S/3 + 24
• F = 3S + 24
• F = 3(S + 24)
