Please explain how 'we' by writing two equations can falsify

You are right, 'we' can't. 'We' need one equation.
this one: f' = Exp(-v/c) f, plus one experimental test.
"Pluss one experimental test".
I see.
It is "one experimental test" that falsifies SR.
So this "one experimental test" proves the SR prediction
for Doppler f' = sqrt ((c+v)/c-v)) f to be wrong.
Which experimental test are you referring to?
Any experimental test that could measure the observed
frequency f' with enough accuracy, given that the
original frequency f and speed v are assumed to be known.
Am I to read this as "I, Albertito, am convinced that
any test where the observed frequency f' is measured with
enough accuracy would prove the equation f' = sqrt ((c+v)/c-v)) f
wrong, but no such experiment is ever actually performed."?

In other words, you are not referring any "one experimental test"
that falsifies SR, because you don't know about any such test.

And if this "one experimental test" really falsifies SR,
what is then the significance of the equation
f' = Exp(-v/c) f?
The significance of f' = Exp(-v/c) f, is that bodies can move
relatively without any upper bound for their relative speeds.
The only equations that can prove SR wrong are obviously
the equations of SR which are used when calculating
the predictions of SR. Any other equations you might devise
are utterly irrelevant when it comes to falsify SR.

It is very simple.
As long as no measurement is done which prove a prediction of SR
wrong, SR isn't falsified.

No, from these two equations we can't prove SR wrong.
What a crazy idea? :-)

"Your theory is crazy, but it's not crazy enough
to be true" [Niels Bohr, to a young physicist]

There is a better way to falsify SR.

There is but one way to falsify any theory.
That is to show that the predictions of the theory
are not compatible with experimental evidence.

Find a theory
that can do the same predictions that SR. A theory
that could even predict phenomena SR can't. Test
that theory with success, proving that it can predict
the same observable phenomena SR can, but with
better accuracy.

OTOH, if your experimental tests only intend to falsify
SR, then if SR is actually falsified, what theory is ready
to replace it?

Certainly not a theory which is falsified by other experiments.

An experiment doesn't have to "intend to falsify" any particular theory.
You do the experiment.
Then you can test different theories to see if their predictions
are compatible with the the outcome of the experiment.
If it is, the theory is confirmed (_not_ proven), if it isn't,
the theory is falsified.
Most experiments confirm several different theories, but it is more
interesting which theories it falsifies.

For example:
MMX confirms SR and the emission theory, but falsifies "Galilean ether".
Sagnac confirms SR and "Galilean ether", but falsifies the emission theory.
Fizeau confirms SR and falsifies your theory.

What is the point with proposing a theory which is falsified
by experiments done more than a century ago?
