To solve the equation \(-2 - 8x = -4x - 2\) using inverse operations, we will isolate the variable \(x\) step by step. Here’s how to do it:

Step 1: Get all \(x\) terms on one side

We can start by adding \(8x\) to both sides of the equation to eliminate the \(-8x\) from the left side.

\[ -2 - 8x + 8x = -4x - 2 + 8x \]

This simplifies to:

\[ -2 = 4x - 2 \]

Step 2: Get the constant terms on the other side

Next, we will add \(2\) to both sides to move the \(-2\) on the right side:

\[ -2 + 2 = 4x - 2 + 2 \]

This simplifies to:

\[ 0 = 4x \]

Step 3: Isolate \(x\)

Next, we divide both sides by \(4\):

\[ \frac{0}{4} = \frac{4x}{4} \]

This results in:

\[ 0 = x \]

Final Answer

The solution to the equation \(-2 - 8x = -4x - 2\) is:

\[ x = 0 \]

You can verify by substituting \(x = 0\) back into the original equation:

\[ -2 - 8(0) = -4(0) - 2 \implies -2 = -2 \]

This confirms that the solution is correct.

Feel free to use any sketch pad or digital tool to visually represent these steps, keeping track of each transformation in the equation.
