Answer 3

Solving the Equation -3x - 9 = -x + 9

To solve the equation -3x - 9 = -x + 9, we need to isolate the variable x on one side of the equation. Here's how we can do it step by step:

Step 1: Simplify both sides of the equation by combining like terms.

On the left side, we have -3x - 9. On the right side, we have -x + 9.

Combining like terms, we get:

-3x - 9 = -x + 9

Step 2: Move all terms containing x to one side of the equation.

To do this, we can add x to both sides of the equation:

-3x - 9 + x = -x + 9 + x

Simplifying further, we get:

-2x - 9 = 9

Step 3: Move the constant term to the other side of the equation.

To do this, we can add 9 to both sides of the equation:

-2x - 9 + 9 = 9 + 9

Simplifying further, we get:

-2x = 18

Step 4: Solve for x.

To solve for x, we need to isolate x. We can do this by dividing both sides of the equation by -2:

(-2x)/-2 = 18/-2

Simplifying further, we get:

x = -9

Therefore, the solution to the equation -3x - 9 = -x + 9 is x = -9.
