1. Solving for One Variable in Terms of Another Variable

2. Solve the equation for b.
A = bh Which variable am I solving for?
h h Divide by h on both sides.
A = b Solved for b. h

3. Solve the equation for h.
A = bh Which variable am I solving for?
b b Divide by b on both sides.
A = h Solved for h. b

4. Solve the equation for h.
V = lwh Which variable am I solving for?
lw lw Divide by lw on both sides.
V = h Solved for h. lw

5. Solve the equation for w.
V = lwh Which variable am I solving for?
lh lh Divide by lh on both sides.
V = w Solved for w. lh

6. Solve the equation for .
A = r Which variable am I solving for?
r r Divide by r2 on both sides.
A =  Solved for . r2

7. Solve the equation for w.
P = 2l + 2w Which variable am I solving for?
-2l -2l Subtract 2l from both sides.
P – 2l = 2w Can’t combine P and -2l
Divide both sides by 2.
P – 2l = w Solved for w

8. Solve the equation for h.
A = bh Which variable am I solving for?
b b Divide by b on both sides.
A = h Multiply both sides by 2. b
(2) A = h(2) Multiply both sides by b
2A = h Solved for h b

9. Solve the equation for .
V = r2h Which variable am I solving for?
r2h r2h Divide by r2h on both sides.
V =  Solved for . r2h

10. Solve the equation for z.
x + y + z = P Which variable am I solving for?
-x -y x -y Subtract x and y from both sides.
z = P – x – y Can’t combine P, -x and -y
z = P – x – y Solved for z.

11. Solve the equation for n.
 - l= m Which variable am I solving for?
+l +l Add l to both sides.
 = m + l Can’t combine m and l
(k) = k(m + l) Multiply both sides by k.
n = km + kl Solved for n.

12. Solve the equation for y in terms of x.
5x + 6y = Which variable am I solving for?
-5x x Subtract 5x from both sides.
6y = -5x Can’t combine -5x and 24
Divide by 6.
y = -x Solved for y.
