Solving Formulas Literal Equations

Rewrite this formula and solve for the variable h. A = ½ b h

• h = 2A / b

• h = A - ½b

• h = 2A - b

• h = A / b

Solve:
V = πr²h , for h

• V/(πr²) = h

• V - πr² = h

• V + πr² = h

• V/π = h

solve for R

pV = nRT

• R= pV/nT

• R= p/n + V/T

• R= pV - nT

• R= (pV-n)/T

Solve for y

-4x + 2y = -6

• y = -2x + 3

• y = 2x + 3

• y = 2x - 3

• y = -2x - 3

Solve for t.
D= rt

• D/r = t

• Dr = t

• D/t = r

• Dt = r

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

• w = a / x

• w = x / a

• w = ax

• x = wa

Solving for a variable means:

Getting a variable ______________

• to cancel

• equal to a number

• by itself

• to simplify

Solve for y

x = 3y - 24

• y = (x + 24)/3

• y = x/3 + 24

• y = 3x + 24

• y = 3(x + 24)

Solve for x:

• x = yb - v

• x = by - v

• x = by + v

• (2.5+h)f
• g=1
• f(5+h)/2
• (5f+h) / 2
