3 people didn't come, the remaining 30 pens, 6 left after the send, 24 of the 30 were sent out, and each person who arrived sent two, that is, 12 people. ConclusionA total of 15 people participated in the sports meeting, and 12 people actually participated in the sports meeting.

Set: There are x number of students who should participate in the sports day.

10x-12(x-3)=6

10x-12x+36=6

2x=-30x=15

So, 15 people were supposed to come, but 12 people actually came.

Let the x-person equation be.

12（x—3）+6=10x

The solution is x=15

i.e. 15 people.

There were 15 people who actually participated in the Games.

5 cabinets with 5 doors, multiplied by 5 finally equals 100

1: Let a+b=m a-b=n so the original formula = (n+4ab n)(m-4ab m)=mn+4abm n-4abn m-16a b mn

mn+4abm²/mn-4abn²/mn-16a²b²/mn

mn+4ab(m²-n²-4ab)/mn=mn+4ab(a²+2ab+b²-a²+2ab-b²-4ab)/mn

mn+4ab·0/mn=mn=(a+b)(a-b)=a²-b²

Because a=3 2, b=-1 2, then a-b =2

2: Because a*b=1 a+1 b, (x-2)*(x-4)=1 (x-2)+1 (x-4)=1 (2-x).

Shift: 2 (x-2)+1 (x-4)=0 Multiply both sides by (x-2) (x-4) at the same time

Get: 2x-8+x-2=0 3x=10 x=10 3

1. It is done with complete squares, and then substituted.

2. Change the two factors before the equal sign to the reciprocal, and then go to the denominator.
