Question

c is the reciprocal (multiplicative inverse) of (a + b). If a = -4 and c = 14, then what is the value b?​

Answer 1

Step-by-step explanation:

$c = 14 \\ \frac{1}{(a + b)} = 14 \\ a + b = \frac{1}{14} \\ - 4 + b = \frac{1}{14} \\ b = \frac{1}{14} + 4 \\ b = \frac{1 + 56}{14} \\ b = \frac{57}{14}$
