x = 5.
I attached an image of my work!
Step 1: Subtract 8 from both sides
4x = 20
Step 2: Divide each side by 4
x = 5

a)
F = (K - 273.15) + 32
<u>- 32</u> <u> - 32</u>
F - 32 = (K - 273.15)
(F - 32) = [(K - 273.15)]
(F - 32) = K - 273.15
- = K - 273.15
- 57.6 = K - 273.15
<u> + 273.15</u> <u> + 273.15 </u>
- 215.55 = K
b)
- 215.55 = K
324 - 215.55 = K
108.45 = K
We can compare the two units or object performances by that.... even in the case of magnitude lower than zero....
