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:
 52x -15y = 0    (1)
 
373
100
x + y = -105    (2)
Question solving process:

Multiply both sides of equation (1) by 373
Divide the two sides of equation (1) by 5200, the equation can be obtained:
         
373
100
x 
1119
1040
y = 0    (3)
, then subtract both sides of equation (3) from both sides of equation (2), the equations are reduced to:
 52x -15y = 0    (1)
 
2159
1040
y = -105    (2)

Multiply both sides of equation (2) by 15600
Divide both sides of equation (2) by 2159, get the equation:
         
1905
127
y = 
1638000
2159
    (4)
, then add the two sides of equation (4) to both sides of equation (1), get the equation:
 52x = 
1638000
2159
    (1)
 
2159
1040
y = -105    (2)

The coefficient of the unknown number is reduced to 1, and the equations are reduced to:
 x = 
31500
2159
    (1)
 y = 
109200
2159
    (2)


Therefore, the solution of the equation set is:
x = 
31500
2159
y = 
109200
2159


Convert the solution of the equation set to decimals:
x = -14.590088
y = -50.578972
