The former formula is written that the (X- 1) power of 2 is equal to 5/2 -X, and the latter formula is written that the logarithm (X- 1) based on 2 is equal to 5/2-x, the (X- 1) power of 2 and the logarithm (X- 1) based on 2. The images of these two equations are symmetrical about Y=X- 1, the slope of Y=5/2-X is-1, and Y=X-65438. Therefore, the coordinates of the midpoint of the intersection of the (X- 1) power sum of Y=5/2-X and Y=2 logarithm (X- 1) are the coordinates of the intersection of Y= x-1and y = 5/2-x.
