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 = 0    (1)
- 
3659
10000
x + y = 0    (2)
 
17659
10000
x - 
7659
10000
y + z = 1    (3)
Question solving process:

Multiply both sides of equation (1) by 3659
Divide the two sides of equation (1) by 10000, the equation can be obtained:
         
3659
10000
x = 0    (4)
, then add the two sides of equation (4) to both sides of equation (2), the equations are reduced to:
 x = 0    (1)
 y = 0    (2)
 
17659
10000
x - 
7659
10000
y + z = 1    (3)

Multiply both sides of equation (1) by 17659
Divide the two sides of equation (1) by 10000, the equation can be obtained:
         
17659
10000
x = 0    (5)
, then subtract both sides of equation (5) from both sides of equation (3), the equations are reduced to:
 x = 0    (1)
 y = 0    (2)
- 
7659
10000
y + z = 1    (3)

Multiply both sides of equation (2) by 7659
Divide the two sides of equation (2) by 10000, the equation can be obtained:
         
7659
10000
y = 0    (6)
, then add the two sides of equation (6) to both sides of equation (3), the equations are reduced to:
 x = 0    (1)
 y = 0    (2)
 z = 1    (3)


Therefore, the solution of the equation set is:
x = 0
y = 0
z = 1
