if you are just after the number of solutions for rather than the solutions themselves, you can just sketch them and count how many times they intersect.

hello : put f(x)=sin(x) and g(x)=x/100 study the intersection of two graphs f,g remark: -1 <= sin(x) <=1

I think :-1<= x/100<=1
i'm pretty sure for ,
this might give you more of idea....
