Which of the following are algebric equations?
`a. 3x-5" " b. 44" "c. 5x " " d. 3xx5+18" "e. 2-p`

Answer

To determine which of the given options are algebraic equations, we need to understand what an algebraic equation is. An algebraic equation is an expression that contains at least one variable and may also include constants. Let's analyze each option step by step.

### Step-by-Step Solution:

1. **Option a: 3x - 5**
- This expression contains a variable (x) and a constant (-5).
- Since it contains a variable, it is an algebraic equation.

**Conclusion: This is an algebraic equation.**

2. **Option b: 44**
- This expression does not contain any variables; it is just a constant.
- Since it lacks a variable, it is not an algebraic equation.

**Conclusion: This is not an algebraic equation.**

3. **Option c: 5x**
- This expression contains a variable (x) and does not have any constant term.
- Since it contains a variable, it is an algebraic equation.

**Conclusion: This is an algebraic equation.**

4. **Option d: 3xx5 + 18**
- This expression contains a constant (18) and a variable term (3xx5). However, "xx" is not a standard notation for multiplication; it should be written as 3 * 5.
- Regardless, since it contains a variable, it is still considered an algebraic equation.

**Conclusion: This is an algebraic equation.**

5. **Option e: 2 - p**
- This expression contains a variable (p) and a constant (2).
- Since it contains a variable, it is an algebraic equation.

**Conclusion: This is an algebraic equation.**

### Final Summary:
- **Algebraic equations identified:**
- a. 3x - 5 (Yes)
- b. 44 (No)
- c. 5x (Yes)
- d. 3xx5 + 18 (Yes)
- e. 2 - p (Yes)
