–13 −

= –4

1 answer

To solve the equation \(-13 - x = -4\), you can isolate \(x\) by following these steps:

  1. Add 13 to both sides of the equation:

    \[ -13 - x + 13 = -4 + 13 \]

    This simplifies to:

    \[ -x = 9 \]

  2. Now, multiply both sides by -1 to solve for \(x\):

    \[ x = -9 \]

So, the solution is:

\[ x = -9 \]
