Write each of the following statements in equation:
A number x increased by 5 equals 12.

Answer

To write the statement "A number x increased by 5 equals 12" in the form of an equation, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the variable**: The statement mentions "a number x". Here, we will use the variable \( x \) to represent this unknown number.

**Hint**: Look for the part of the statement that refers to an unknown quantity.

2. **Translate "increased by"**: The phrase "increased by 5" means we need to add 5 to the number \( x \). This can be expressed mathematically as \( x + 5 \).

**Hint**: When you see "increased by", think of addition.

3. **Set up the equation**: The statement says that this sum (the number \( x \) increased by 5) is equal to 12. In mathematical terms, we express this as:

\[ x + 5 = 12 \]

**Hint**: Look for the word "equals" to know where to place the equal sign in your equation.

### Final Equation:

Thus, the equation representing the statement "A number x increased by 5 equals 12" is:

\[ x + 5 = 12 \]
