this is what i come up with:

Simplifying

x + -7 = x + 19

Reorder the terms:

-7 + x = x + 19

Reorder the terms:

-7 + x = 19 + x

Add '-1x' to each side of the equation.

-7 + x + -1x = 19 + x + -1x

Combine like terms: x + -1x = 0

-7 + 0 = 19 + x + -1x

-7 = 19 + x + -1x

Combine like terms: x + -1x = 0

-7 = 19 + 0

-7 = 19

Solving

-7 = 19

The left and right sides are not equal, therefore there is no solution.

The left and right sides are not equal, therefore there is no solution.

Yes both sides ARE equal.

The statement SAYS they are.

The question is therefore ...what is the value of X.

Like most people your just trying too hard and are over looking the simple way to solve the problem while the answere is right in front of you with neon lights pointing it out...so to speak.

I see people do this all the time when trying to make a cheat work or bypass an anti-cheat system.

Just stop thinking so hard.

The answere is -very- simple!

With a -simple- puzzle like this those schooled in "higher" ways of working things out almost always fail becuase they are trying to use everything they have been taught to figuare it out.

That is the wrong way to think.

It is like training for self protection...follow the basics and the body does without the mind stopping to think about it.

Relax your mind and let it go back to the basics.

Put yourself back on autopilot (yes I flew aircraft and have a licence...still).
