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).
