Answer in true or false:
x, y, 23 are all variables.

Answer

To determine whether the statement "x, y, 23 are all variables" is true or false, let's analyze each part of the statement step by step.

### Step 1: Identify what a variable is
A variable is a symbol used to represent an unknown value. In algebra, common variables include letters such as x, y, and z.

**Hint:** Remember that variables can change or vary, while constants remain the same.

### Step 2: Identify the elements in the statement
The statement includes:
- x
- y
- 23

**Hint:** Break down the statement into its components to analyze them individually.

### Step 3: Analyze x and y
Both x and y are letters that can represent different values. Therefore, they are considered variables.

**Hint:** Think about how variables can take on different values in equations.

### Step 4: Analyze the number 23
The number 23 is a specific value and does not change. It is a constant, not a variable.

**Hint:** Constants are fixed values that do not change, unlike variables.

### Step 5: Combine the analysis
Since x and y are variables but 23 is a constant, not all three elements (x, y, and 23) are variables.

**Hint:** Consider the overall statement and whether all parts fit the definition of a variable.

### Conclusion
The statement "x, y, 23 are all variables" is **False** because 23 is a constant, not a variable.

**Final Answer:** False
