Chapter 4.4, Problem 21PPS

To determine

To solve and check: the given equation

Answer to Problem 21PPS

The required solution is $b=-64$

Explanation of Solution

Given:

  $16=-\frac{b}{4}$

Calculation:

Multiply both sides of equation by $-4$

  $\begin{array}{l}b=16\left(-4\right)\\ b=-64\end{array}$

Solution:- $b=-64$

Check

Substitute $b=-64$ in $16=-\frac{b}{4}$

  $16=-\frac{\left(-64\right)}{4}$

  $16=16$

Left hand side = Right hand side

Hence verified.

So solution is $b=-64$

Conclusion:

Therefore, the required solution is $b=-64$
