How do you find the length of each of the sides of a square if the perimeter is 39 yards?

Step-by-step explanation:

Given:

The given inequality is:

The given inequality has variable 'x' on both sides of the inequality.

In order to solve such inequalities, we bring the variables on the same side as the first step in solving for 'x'.

Therefore, we could either add on both sides or add both sides to bring the variable terms on same side.

If we add both sides, we get:

So, among all the given options, third option matches the above inequality.

Therefore, the first step in solving the given inequality is
