The first step in solving the equation 5+|2x−4|=9 is to isolate the absolute value expression. What is the first step to isolate the absolute value expression? Divide both sides of the equation by 2. Subtract 9 from both sides of the equation. Subtract 5 from both sides of the equation. Add 4 to both sides of the equation.

Subtract 5 from both sides of the equation.

Step-by-step explanation:

Given the function:

First step to solve the above equation is to isolate the absolute value function i.e. one side(either Left Hand Side or Right Hand Side) of equation must contain the terms containing the absolute function only.

In Left Hand Side, we have the absolute value function added to 5.

If we subtract 5 from both the sides, we get:

So, after "subtracting 5 from both sides of the equation", the absolute function gets isolated on the left hand side of the equation i.e. Left Hand Side contains the absolute value function only.
