Unable to eliminate the algebraic loop when there is an exponential term within?

Hello,

I am trying to use Algebraic Constraint to eliminate the algegraic loop. Howevr, I've found that when there is an exponential term within the loop,I am unable to do this.

I am using following example as a test:

x = 3 - 4*exp(0.1*(5+3*x))

When using following structure in MATLAB R2014b

No surprise that there is an algebraic loop warning. So I've change it to

Although the result is correct, the algebraic loop still exists

Did I do anything wrong here or how to eliminate the algebraic loop in this case?

Thanks a lot.
