F = 9/5C + 32
Subtract 32 to both sides:
F - 32 = 9/5C
Divide 9/5 to both sides or multiply by its reciprocal, 5/9:
5/9(F - 32) = C
Simplify:
C = 5/9F - 160/9
All to one side:
4x^2-32x+64 = 0,
divide by 4:
x^2 -8x + 16 = 0
apply formula or see that it is (x-4)^2!, so only x =4 is a root and it is double.

Step-by-step explanation:

__________________________________________________________

- Rearrange the equation by subtracting what is to the right of the greater than sign (≤, ≥) from both sides of the inequality:

- Divide both sides by
:
- Remember to flip the inequality sign:
- Subtract
from both sides:
