Solving Literal Equations Formula

Solve the formula for r.   What is the 1st step?

• Divide each side by t. 

• Subtract t from each side. 

• Add t to each side. 

• Multiply each side by t. 

S = 3F - 24  Solve for F

• F = (S + 24)/3

• F = S/3 + 24

• F = 3S + 24

• F = 3(S + 24)

8x + 4y= 16 for y

• y = -8x + 16

• y = 2x -4

• y = -2x + 4

• y = -8x + 12

Solve for s:
2s = 6t + 8w

• s = 12t + 16w

• s = 6t + 4w

• s = 3t - 4w

• s = 3t + 4w

M= i + r ; solve for r

• M-i

• M+i

• -M-r

• -M+i

Solve the formula for b.  What is the 1st step? 

• Subtract h from each side. 

• Add h to each side. 

• Divide each side by h. 

• Multiply each side by 2. 

Solve for 'x': x + 2w = m

• x = m - 2w

• x = 0.5m - w

• x = 2mw

• x = m/(2w)

Solve for w:
A = LW

• A = ^L/_W

• w = ^L/_A

• w = A

• w = ^A/_L

• h=V/(3πr²)
• h=(3V)/(πr²)
• h=V/(3πr²)
• h=(3π)/(Vr²)

Solve the formula for y. What is the 1st step?

• Subtract B from each side.

• Divide each side by Ax.

• Divide each side by B.

• Subtract Ax from each side.
