1.   C = ⁵/₉F - 32
9C = 9(⁵/₉F - 32)
  9C = 9(⁵/₉F) - 9(32)
  9C = 5F - 288
- 5F - 5F
  9C - 5F = -288
- 9C   - 9C
-5F = -9C - 288
-5 -5
F = 1⁴/₅C + 57.6

2. $H = w + \frac{50}{m^{2}}$
   $m^{2}(H) = m^{2}(\frac{50}{m^{2}})$
   $Hm^{2} = 50$
   $\frac{Hm^{2}}{H} = \frac{50}{H}$
   $m^{2} = \frac{50}{H}$
   $\sqrt{m^{2}} = \sqrt{\frac{50}{H}}$
   $m = \frac{\sqrt{50}}{\sqrt{H}}$
   $m = \frac{5\sqrt{2}}{\sqrt{H}}$
   $m = \frac{5\sqrt{2}}{\sqrt{H}} * \frac{\sqrt{H}}{\sqrt{H}}$
   $m = \frac{5\sqrt{2H}}{H}$

3. A = 5 + 4√x
- 5 - 5
  A - 5 = 4√x
  (A - 5)² = (4√x)²
  A² - 10A + 25 = 16x
16 16
¹/₆A² - ⁵/₈A + 1⁹/₁₆ = x

4. $A = \frac{b + c}{b}$
   $Ab = b(\frac{b + c}{b})$
   $Ab = b + c$
   $Ab - b = c$
   $b(A) - b(1) = c$
   $b(A - 1) = c$
   $\frac{b(A - 1)}{A - 1} = \frac{c}{A - 1}$
   $b = \frac{c}{A - 1}$
