The number 9 doesn't appear to ask a question that needs an answer.
x + 9 = 26Only one lonely number belongs to the group of solutions of this equation.The number is 17.
[x + y = 6] has an infinite number of solutions.
an infinite number of solutions
If you mean: x2+8x-9 = 0 then the solutions are x = 1 and x = -9
Infinite.

There is not a unique answer. (3,36) and (9,12) are two possible solutions.
It does not have any solutions! 14.8 is a number, not an equation, inequality or question and so has no solutions.
That is an equation, with an infinite number of solutions. It simplifies to y = 2/3 * x - 2. Two solutions are x = 6, y = 2, and x = 9, y = 4.
There are infinitely many solutions to 11x - 99 = 11(x - 9)
There is no number that satisfies this question as written. If you have omitted the decimal point between the 7 and 9 in the first number, then there are an infinite number of solutions, including 7.924, 7.925 and 7.926
