200+25 = 225 is one possibility.
no it can't be
7-2 IS positive. You do not need an equation for it. And if it were not positive, no correct equation would show it to be positive.
The equation above is correct.
yes
It really depends on the type of equation, but in the simpler cases - those that you are likely to encounter in high school algebra - you will usually need to replace the purported solution into the original equation, then simplify the equation as appropriate. If this results in a true statement (for example, "5 = 5"), then the solution is correct; if you get a false statement (for example, "1 = 0"), then the purported solution is not correct.

1150 is bigger.
It is: 9/400 in its lowest terms.
The correct set of coefficient for an equation depends with the equation in question. There are many types of equations.

if an equation is given the correct answer, it is mathematically correct.
2111.Equation coefficients are needed to write a correct chemical equation
That depends what the original equation is.
A skeleton equation has all the correct reactants and products but it does not have the coefficients that indicate the stoichiometric proportions.
