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

You're allowed to do that, yes. Whether or not it "solves" any particular equation depends on the equation itself.
There is no set limit on the number of negative words allowed in a clause. However, excessive use of negative words can make the sentence confusing or difficult to understand. It is generally recommended to limit the use of negative words for clarity and readability.
In a standard poker game, the maximum number of players allowed per table is typically 9 or 10.
