Answer 2

X= (-1,9)

The expression "X= (-1,9)" seems to represent a range of values for the variable X, rather than a specific mathematical equation. The notation "X= (-1,9)" typically indicates that X can take any value between -1 and 9, excluding -1 and 9 themselves. This is known as an open interval.

The notation "X= (-1,9)" can be interpreted as the set of all real numbers x such that -1 < x < 9. In interval notation, this can be represented as (-1, 9).
