Solve Literal Equations

Solve for t.
D= rt

• D/r = t
• Dr = t
• D/t = r
• Dt = r

pV = nRT
solve for R

• R= pV/nT
• R= p/n + V/T
• R= pV - nT
• R= (pV-n)/T

What should we do first to solve for x?
y=mx+b

• Add
• Subtract
• Multiply
• Divide

• b = 3A - a - c
• b = -3A + a - c
• b = -3A - a - c 
• b = 2A - c

Solve -2 = 4r + s for s.

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

Solve:
y = mx + b , for b

• y - mx = b
• y + mx = b
• y/mx = b
• y + mx = -b

Solve:
8x + 4y = 16    ,  for     y

• y = -2x + 4
• y = 2x - 4
• y = 2x + 4
• y = -2x - 4

Solve:
12x - 4y = 20  ,  for   y 

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

5x - y = 16

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

Solve:
V = πr²h , for h

• V/(πr²) = h
• V - πr² = h
• V + πr² = h
• V/π = h
