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 
17689
10000
y = 
2793
50
    (1)
43
50
x + y = 
1543
50
    (2)
Question solving process:

Multiply both sides of equation (1) by 43
Divide the two sides of equation (1) by 50, the equation can be obtained:
         
43
50
x 
760627
500000
y = 
120099
2500
    (3)
, then add the two sides of equation (3) to both sides of equation (2), the equations are reduced to:
 x 
17689
10000
y = 
2793
50
    (1)
260627
500000
y = 
197249
2500
    (2)

Multiply both sides of equation (2) by 884450
Divide both sides of equation (2) by 260627, get the equation:
        
271190059
153310000
y = 
161165947
2606270
    (4)
, then subtract both sides of equation (4) from both sides of equation (1), get the equation:
 x = 
38949262
6515675
    (1)
260627
500000
y = 
197249
2500
    (2)

The coefficient of the unknown number is reduced to 1, and the equations are reduced to:
 x = 
38949262
6515675
    (1)
 y = 
39449800
260627
    (2)


Therefore, the solution of the equation set is:
x = 
38949262
6515675
y = 
39449800
260627


Convert the solution of the equation set to decimals:
x = -5.977779
y = -151.364978
