5x-8=3x
As long as you do the same thing on both sides of the equal sign you're fine; the equation is still the same. For a start you can add 8 on both sides.
This means that 5x-8+8=3x+8
Next let's subtract 3x from both sides.
This means that 5x-8+8-3x=3x+8-3x.
The left side is now equal to 2x while the right side is equal to 8.
In other words, 2x=8.
Divide by two on each sides. This means that x=4.

If the television was not a new one you could explain that the value of the old television was not the same value as a new one. Also, be calm and explain to them that it was an accident and you feel sorry that it happened.
