Solve (x + 1 < 5) ∩ (x - 4 > -3). {all real numbers} x x < 4 or x > 1

Question

Solve (x + 1 < 5) ∩ (x - 4 > -3).

{all real numbers}
1 < x < 4
x < 4 or x > 1

Answer 1

1 < x < 4

Explanation:

Answer 2

`(x + 1 \ \textless \ 5)\,\cap\,(x - 4 \ \textgreater \ -3)\\\\(x\ \textless \ 5-1)\,\cap\,(x\ \textgreater \ -3+4)\\\\(x\ \textless \ 4)\,\cap\,(x\ \textgreater \ 1)\\\\(-\infty;4)\,\cap\,(1;\infty)\\\\(1;4)\\\\\\\boxed{\\,1\ \textless \ x\ \textless \ 4\}`
