ANSWER

b = 5\frac{2}{3}

EXPLANATION

The given equation is

\frac{6}{b - 1} = \frac{9}{7}

where b≠1.

We cross multiply to get,

7 \times 6 = 9(b - 1)

Expand and multiply out to get,

42 = 9b - 9

Group similar terms,

42 + 9 = 9b

9b = 51

Divide both sides by 9

b = \frac{51}{9}

Simplify:

b = \frac{17}{3}

Or

b = 5\frac{2}{3}
