Describing to someone your height; It would be nonsense telling you have -1 meter, for example.
Describing your age; An age of -3 years is meaningless.

3(x+2) = 3x+6
Distributive property
(3)(x)+(3)(2) = 3x+6
3x+ 6 = 3x+6
Now subtract 3x from both sides
3x+6-3x = 3x+6-3x
6=6
Subtract 6 from both sides
6-6 = 6-6
0=0
