To determine

To solve and check: the given equation

Answer to Problem 20PPS

The required solution is $b=-972$

Explanation of Solution

Given:

  $\frac{b}{9}=-108$

Calculation:

Multiply both sides of equation by 9

  $\begin{array}{l}b=-108\left(9\right)\\ b=-972\end{array}$

Solution:- $b=-972$

Check:

Substitute $b=-972$ in $\frac{b}{9}=-108$

  $\frac{-972}{9}=-108$

  $-108=-108$

Left hand side = Right hand side

Hence verified.

So solution is $b=-972$

Conclusion:

Therefore, the required solution is $b=-972$
