ANSWER

$n < - 3 \: or \: n - 2$

EXPLANATION

The given inequality is,

$|2n + 5| \: \: 1$

By the definition of absolute value,

$- (2n + 5) \: \: 1 \: or \: (2n + 5) \: \: 1$

We divide through by negative 1, in the first part of the inequality and reverse the sign to get,

$2n + 5 \: < \: - 1 \: or \: (2n + 5) \: \: 1$

We simplify now to get,

$2n \: < \: - 1 - 5 \: or \: 2n \: \: 1 - 5$

$2n \: < \: - 6 \: or \: 2n \: \: - 4$

Divide through by 2 to obtain,

$n \: < \: - 3 \: or \: n \: \: - 2$
