Multiply the equation by negetive 1. So, -2x+y=1 becomes 2x-y=-1.
It depends on the domain of y. If that is restricted to non-negative values, then the answer is yes. But if y is allowed to be negative, then the answer is no because then there are two values of y for each non-zero value of x.
No solution. A negative number is not allowed.
yes -a=-b means you multiplied each side by -1 which is allowed
No running allowed! Never jog alone at night.
When a law is allowed to stand because it is reasonably related to a legitimate government interest.

Yes.
Identity.
Coefficients of molecules are adjusted.
You're allowed to do that, yes. Whether or not it "solves" any particular equation depends on the equation itself.
The reasonableness standard is a legal principle that requires actions or decisions to be justifiable, understandable, and rational based on the circumstances. It is often used in legal contexts to assess whether a person's conduct meets an objective standard of reasonableness.
