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:
 1135x + 120y = 
55273
25
    (1)
 
4415
4
x + 
2079
20
y = 
40799
20
    (2)
Question solving process:

Multiply both sides of equation (1) by 883
Divide the two sides of equation (1) by 908, the equation can be obtained:
         
1002205
908
x + 
26490
227
y = 
48806059
22700
    (3)
, then subtract both sides of equation (3) from both sides of equation (2), the equations are reduced to:
 1135x + 120y = 
55273
25
    (1)
57867
4540
y = 
1249597
11350
    (2)

Multiply both sides of equation (2) by 181600
Divide both sides of equation (2) by 19289, get the equation:
        
2314680
19289
y = 
243569008
4378603
    (4)
, then add the two sides of equation (4) to both sides of equation (1), get the equation:
 1135x = 
293902861
109465075
    (1)
57867
4540
y = 
1249597
11350
    (2)

The coefficient of the unknown number is reduced to 1, and the equations are reduced to:
 x = 
293902861
311191459
    (1)
 y = 
2499194
289335
    (2)


Therefore, the solution of the equation set is:
x = 
293902861
311191459
y = 
2499194
289335


Convert the solution of the equation set to decimals:
x = 0.944444
y = 8.637718
