Rewrite Equations

solve for R

pV = nRT

• R= pV/nT

• R= p/n + V/T

• R= pV - nT

• R= (pV-n)/T

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

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

Answer explanation

m is being multiplied by c², so we need to divide both sides of the equations by c² to give us  $m=\frac{e}{c²}$  

8x + 4y= 16

• y = -8x + 16
• y = 2x -4
• y = -2x + 4
• y = -8x + 12

Answer explanation

F is being multiplied by  $\frac{5}{9}$  , so we need to multiply both sides of the equation by the reciprocal  $\frac{9}{5}$  . Then we need to add 32 to both sides of the equation, leaving us the formula.

 $F=\frac{9}{5}C+32$  

Solve the literal equation for the given variable.

• 2A/h
• 2/(h)
• 2Ah
• Ah/2

Solve for the indicated variable.

• A = l/w
• w = l/A
• w = A
• w = A/l

Solve x = w / a for w.

• w = a / x

• w = x / a

• w = ax

• x = wa
