How can I build expression dynamically by variable.

If I Have An Expression "ax + bx + cx = 0"

Also having a variable of this expression "a"

If I Pass This Expression To a Function With Variable GetExpression(exp, var){

Expression Should be return as "a = -(bx + cx)/x"

return "a = -(bx + cx)/x"

}

Variable Can be changed As Well as Expression Can Be Changed..

@Sana Ullah: do you have the Symbolic Toolbox available to use?
