On line solution of multivariate equations:
    First set the elements of the equation (i.e. the number of unknowns), then click the "Next" button to enter the coefficients of each element of the equation set, and click the "Next" button to obtain the solution of the equation set.
    Note that the coefficients of each element of the equation system can only be numbers, not algebraic expressions (including mathematical functions).

detailed information:
The input equation set is:
 
12559
125
A + 
105561
500
B = 
1903
25
    (1)
 
4703
25
C + 
6503
25
D = 
3478
25
    (2)
0 = 0    (3)
0 = 0    (4)
0 = 0    (5)
Question solving process:

The coefficient of the unknown number is reduced to 1, and the equations are reduced to:
 A + 
105561
50236
B = 
9515
12559
    (1)
 C + 
6503
4703
D = 
3478
4703
    (2)
0 = 0    (3)
0 = 0    (4)
0 = 0    (5)


Therefore, the solution of the equation set is:
A = 
9515
12559
 - 
105561
50236
B
C = 
3478
4703
 - 
6503
4703
D


Convert the solution of the equation set to decimals:
A = 0.757624 - 
105561
50236
B
C = 0.739528 - 
6503
4703
D

Where:  B, D, E are arbitrary constants.
