Question 31917: Temperature-F and C scales. Both these scales are linear---is there any point when F = C? What would it be and how did you find it?

Use the formula C/5=(F-32)/9
If there is a point when F=C, say = x
x/5=(x-32)/9
=>9x = 5(x-32)
=>9x = 5x-160
=>4x=-160
=>x=-40
The answer is -40; meaning: -40 degree F = -40 degree C
