Let's take a look at the question.
00:02
So for question 8, we're looking forward to find the temperature that will coincide between the degree celsius and degree fahrenheit.
00:09
Well, we know the equation from converting degree fahrenheit to degree celsius is tc equal to five of nine times tf minus 32.
00:18
So let's say that tc and tf both at the same degree, okay? which means that will coincide.
00:26
So let's say the temperature was x.
00:28
So now let's plug in x.
00:30
We got x equal to 5 over 9 times x minus 32.
00:35
Okay, if we do some math, you'll give us x equal to 5 over 9 x minus.
00:48
Actually, let's do a, i think, let's do a quick way.
00:52
Okay.
00:54
So this will give us 9 over 5x equal to x minus 32.
01:03
Okay...
