Please take a look at my question and ask the expert to help me explain

Actually, it's okay, I've had dreams like that, sometimes I can see people killed, of course, it's not very bloody, it's just a twist of his neck, and sometimes, for example, fighting with people, but I just can't do it, in fact, it's just a dream, it's just a dream, 1 is thinking that I watch too much TV, 2, it's because I'm too tired, 3 is a dream, maybe it's just a dream, don't care too much.

You have a lot of imagination, you like to watch movies and television, and after watching it, you don't consciously associate it, it's okay.

Buddhism says that dreams are the shadow of past lives. Psychology says that dreams are projections of the subconscious. Maybe everyone has an explanation, the key is which one you yourself believe.

Honestly, aren't you bored these days? Otherwise, if you're also in college, why don't you have nothing to do and hold on to a few of your dreams.

Well, that's interesting!

I read a few of the answers above, and they probably didn't make any sense.

I suggest you go find a jacket and take a look. Or go to the temple to ask for a lot, it feels like a weird dream!

Thinking every day, dreaming every day.

a-b+c=0 ①

4a+2b+c=3 ②

25a+5b+c=60 ③

Will - available.

25a+5b+c-a+b-c=60-0

24a+6b=60 ④

Will - available.

4a+2b+c-a+b-c=3-0

3a+3b=3

a+b=1 ⑤

Will - 6, available.

24a+6b-6a-6b=60-6

18a=54

The solution is a=3 and the substitution of a=3 can be obtained.

3+b=1 gives b=-2

Substituting a=3, b=-2 into obtains.

3-（-2）+c=0

The solution yields c = -5

The solution of this system of equations is a=3, b=-2, c=-5

According to Eq. 1, a=b-c, b=a+c, c=b-a; Bring in the formula 2---4x(b-c)+2x(a+c)=4b-4c+2a+2c=, bring c into ---2a+4b-2(b-a)=3, get 4a+2b=3 so c=0;Look at Equation 3 to change into simple:

5（5a+b)+0=60...Remove 5 to get 5a+b=12, because a=b-c=b-0,,, then a=b, 5a+a=12, a=2=b.

The calculation is wrong.

From (1), b=a+c, substituting the last two formulas, 4a+2a+2c+c=3, 25a+5a+5c+c=60, 2a+c=1, 5a+c=10, subtracting the two formulas, 3a=9, a=3, substituting c=-5, b=-2

The first equation is 4, and the second equation minus one gives b

There's nothing to say, Ohm's law, ah......

12V is higher than -4V, so the current flows from the left to the right, so take the right side as the reference point, and the reference voltage is -4V

Next, calculate how much V is higher than the right end at point A, calculate the partial voltage by Ohm's law, and add the reference voltage.

In fact, it is ......the same as the mathematics "what are the coordinates of the point that divides the line segment from -4 to 12 on the coordinate axis into 3:5".

Hope it helps
