Chapter 1, Problem 3CR

To determine

To calculate:

Given equation.

Answer to Problem 3CR

Solution of the given equation will be $n=10$ .

Explanation of Solution

Given information:

  $-\frac{n}{5}=-2$

Calculation:

Here, given equation is $-\frac{n}{5}=-2$ .

For solving the equation, isolate the variable by performing operations to both sides of equation.

For checking substitute the value of variable in the original equation.

  $-\frac{n}{5}=-2$

Multiply both sides by $5$ ,

  $\left(5\right)-\frac{n}{5}=\left(5\right)-2$

Simplify,

  $-n=-10$

Divide both sides by $-1$ ,

  $\frac{-n}{-1}=\frac{-10}{-1}$

Simplify,

  $n=10$

Thus solution of the given equation will be $n=10$ .
