I just wnt to know that in maple programing if i have a set of system of equations in which subscripted variables are used then how we find the solution of that system for example we have set of equations as eq_set:={-v2,1-a2=0 ,3v0,3+2v2,1=0 , -b2+3v3,0-2v1,2=0 , v1,2=0} here we want to find the values of subscripted variables v2,1 ,v0,3 v3,0 , v1,2.Kindly help me.

i want to know that is ther any procedure or builtin functin which return the exponent of a variable.For example if i have a variabl x^2 result will be 2.and also i want to know the procedure by which if i have two lists of variables we can compare there type of variables and cobine the coefficients of same variables.For example >s:=[v1,2*x^2*y,v2,1*x*y^2,v0,3*x^3]; >p:=[a*x^3,b*x*y^2,c*x^2*y]; i want to get result v1,2+c ,v2,1+b, v0,3+a how can i get this result any body help me
