Question

Solve (x + 5 < 4) ∩ (x - 3 > -6).

Answer 1

Hey daren! Welcome to OpenStudy! The symbol "∩" to find what they have in common, or the factor, in this case, would be the "x".

So, in turn, in the equation: \[(x + 5 < 4) ∩ (x - 3 > -6)\] The two equations only have one thing in common, which would be the "x"s. \[x_1 ∩ x^2\]

Answer 2

so all real numbers?

Answer 3

No, it means to find the things in common with both equations, if, for an example, I had: \[(x+6-43) ∩ (6-43+y)\] the answer would be 6, and -43, its not asking what kind of numbers, but what they have in common.
