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:
 x -323y = -28066    (1)
 x -503y = 
803
10000
    (2)
Question solving process:

Subtract both sides of equation (1) from both sides of equation (2) ,the equations are reduced to:
 x -323y = -28066    (1)
-180y = 
280660803
10000
    (2)

Multiply both sides of equation (2) by 323
Divide both sides of equation (2) by 180, get the equation:
        -323y = 
51014017
200000
    (3)
, then subtract both sides of equation (3) from both sides of equation (1), get the equation:
 x = 
1369246721
200000
    (1)
-180y = 
280660803
10000
    (2)

The coefficient of the unknown number is reduced to 1, and the equations are reduced to:
 x = 
1369246721
200000
    (1)
 y = 
93553601
600000
    (2)


Therefore, the solution of the equation set is:
x = 
1369246721
200000
y = 
93553601
600000


Convert the solution of the equation set to decimals:
x = -6846.233605
y = -155.922668
