Solving an algebra problem

When Solving an algebra problem, there are often multiple ways to approach it. Do simple math questions first, and then complex math questions; According to your own actual situation, skip the college entrance examination math questions that are really without ideas, from easy to difficult. And the students also said that the math questions in the college entrance examination were very simple, and they believed that all students could get full marks. The students said this lightly, but we in front of the screen are really trembling. Is this something we can say casually? Don't make mathematics seem very simple.

However, with the increase of variables, Gauss elimination method is gradually difficult to solve. In order to solve the n-ary equations, people began to use determinants to solve the equations, which is Clem's law In practical application, many problems are quite complex, and the differential equations constructed are also extremely complex. It is impossible to get the expression of y = f (x). Fortunately, many problems do not need to solve the expression, only the value of y can be calculated.

It is not a geometric problem, and the (overall area) of two (large triangles) in the geometric figure is still the same. Only the total area formed by the whole set of individuals after cutting according to the measurement data changes differently. Moreover, this change is completely caused by the reversal of the positions of the two (small triangles)..
