Get Character on Both Sides of Delineator

I am working on an algebra calculator. I want to be able to get each of the Characters on either side of the delineator saved as strings.

Example: 5x=2*63
string 1 = x
string 2 = 2.

Below i have the code for splitting the problem at the equals sign.

  Dim chars As String() = TextBox1.Text.Split(New Char() {"="c})
