Step-by-Step Solution

To solve this problem, we'll follow these steps:

Now, let's work through each step:

Step 1: We are given that adding $-3$ to a number $x$ results in $-24$ . This can be written as:
$x + (-3) = -24$ .

Step 2: To isolate $x$ , we add 3 to both sides of the equation, as $-3$ is the term being added:
$x + (-3) + 3 = -24 + 3$ .

Step 3: Simplifying the equation gives us:
$x = -24 + 3$ .
Perform the addition on the right-hand side:
$x = -21$ .

Therefore, the solution to the problem is that the number is $-21$ .
