To correct the belowequation-

  

Answer to Problem 40E

  $m=12$ is the solution.

Explanation of Solution

Given:

  

Equation: $-\frac{m}{3}=-4$

Formula Used:

The multiplication property of equality states that when we multiply both sides of an equation by the same number, the two sides remain equal. 

Calculation:

Given: Equation: $-\frac{m}{3}=-4$

To solve the equation, multiplying $-3$ on both the sides as “multiplication property of equality states that when we multiply both sides of an equation by the same number, the two sides remain equal. 

  $\begin{array}{l}-\frac{m}{3}=-4\\ -\frac{m}{3}\times \left(-3\right)=-4\times \left(-3\right)\\ m=12\end{array}$

Thus, the solution is $m=12$ .

Conclusion:

Hence, the solution is $m=12$ .
