Manipulating Formulas for a Variable

Rewrite this formula and solve for the variable W. P = 2L + 2W

• W = P/2 - 2L

• W = P - 2L

• W = (2L - P) / 2

• W = (P - 2L) / 2

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

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

solve for r

• r=7-ax

• r=7+ax

• r=7ax

Solve for x:

• x = yb - v

• x = by - v

• x = by + v

Solve the following for x:

dx + e = f

• x = (f + e)/d

• x = (f - e)/d

• x = d/(e - f)

• x = d/(e + f)

• h = 2A / b

• h = A - ½b

• h = 2A - b

• h = A / b

• I = V/R

• I = R/V

• I = RV

• I = VR

Rewrite this formula and solve for the variable y. 7y = −28x - 56

• y = −4x + 8

• y = 4x + 8

• y = −4x - 8

• y = 4x - 8

Rewrite this formula and solve for the variable y. 9x + y = 27

• y = 9x - 27

• y = 3 / x

• y = 3x

• y = −9x + 27
