Literal Equations

Solve -2 = 4r + s for s.

• s = -2 + 4r
• s = 2 - 4r
• s = -2 - 4r
• s = 2 + 4r

Solve for x:

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

ax + c = R
(solve for x) 

• ax = R + c
• ax = R - c
• x = a(R-c)
• x = (R-c) / a 

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

What should we do first to solve for x?

Solve:
C = 2πr, for r

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

pV = nRT

solve for n

• n= pV/RT

• n= p/R + V/T

• n= pV - RT

• n= (pV-R)/T
