Chapter 6.4, Problem 35S

To determine

To solve: the given equationfor $x$ .

Answer to Problem 35S

  $x=18$

Explanation of Solution

Given information:

The given equation is

  $7x=126$

Calculation:

Consider the given equation.

  $7x=126$

Now, divide both sides by 7.

  $\frac{7x}{7}=\frac{126}{7}$

Now, simplify as shown:

  $\begin{array}{l}\frac{7x}{7}=\frac{126}{7}\\ \frac{7x}{7}=\frac{7\times 3\times 6}{7}\end{array}$

Cancel out 7.

  $x=18$

Therefore solution for $x$ is,

  $x=18$
