Solving Formulas for a Given Variable

Solve for the indicated variable.

• A = l/w

• w = l/A

• w = A

• w = A/l

Solve:
C = 2πr, for r

• C/(2π) = r

• C + 2π = r

• C - 2π = r

• 2πC = r

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

• 4w-10
• -2w+10
• 2w-10
• -4w + 10

solve for R

pV = nRT

• R= pV/nT

• R= p/n + V/T

• R= pV - nT

• R= (pV-n)/T

Solve for y

x = 3y - 24

• y = (x + 24)/3

• y = x/3 + 24

• y = 3x + 24

• y = 3(x + 24)

Solve for y

-4x + 2y = -6

• y = -2x + 3

• y = 2x + 3

• y = 2x - 3

• y = -2x - 3

Solve for x:

• x = yb - v

• x = by - v

• x = by + v

Solve for t.
D= rt

• D/r = t

• Dr = t

• D/t = r

• Dt = r
