(9 of anything) plus (8 of the same thing) = 17 of them
Yes. I assume you mean (x2 + y2) / (a2 + b2) = 1. Set all the variables to the same value - for example, all equal to one - and you have a valid solution.
Without any equality signs the given terms can't be classed as equations.
That system of equations has no solution. When the two equations are graphed, they turn out to be the same straight line, so there's no such thing as a single point where the two lines intersect. There are an infinite number of points that satisfy both equations.
Multiplying the first equation by -3 gives -21x - 6y = -48 but the other equation gives 24 as the value of the same expression, so you are correct, there is no solution

No.
No.
A dozen is equal to 12, so 2/3 of a dozen is the same as 12x2/3 = 8
The chemical difference between the two solutions is the arrangement of ions: in the KCl+NaBr solution, you have K+, Cl-, Na+, and Br- ions, while in the KBr+NaCl solution, you have K+, Br-, Na+, and Cl- ions. Physically, both solutions will have the same molar density since they contain the same total number of ions in solution.

It seems there might be a typo in your question. If you are asking whether a "solution" is the same as a "solution," then yes, they are the same word. A solution refers to a means of solving a problem or dealing with a difficult situation.
If you start out with a solution and you put the same amount of solution in different types of glassware, it will always be the same no matter what.

Homogeneous. The prefix homo means "the same". A solution is the same throughout.

No, NS and NSS are not the same solution. NS refers to Normal Saline, which is a solution of 0.9% sodium chloride in water. NSS refers to Normal Saline Solution, which is the same as NS. Both terms are commonly used interchangeably to refer to the same solution.
