The image contains three simple algebraic expressions to evaluate:

1. \( 2x \) when \( x = 5 \)
2. \( 4y \) when \( y = -3 \)
3. \( 3z \) when \( z = 1.2 \)

Let's solve each of them:

### a) \( 2x \) when \( x = 5 \)
\[ 2x = 2 \times 5 = 10 \]

### b) \( 4y \) when \( y = -3 \)
\[ 4y = 4 \times (-3) = -12 \]

### c) \( 3z \) when \( z = 1.2 \)
\[ 3z = 3 \times 1.2 = 3.6 \]

So, the results are:
- a) 10
- b) -12
- c) 3.6

Would you like more details or have any other questions?

Here are 5 related questions:
1. How do you evaluate expressions with multiple variables?
2. How would the result change if \( x \) was negative in part a)?
3. What happens when multiplying by fractions in algebraic expressions?
4. How does the distributive property affect simple algebraic calculations?
5. Can you explain how to solve two-variable expressions like \( 2x + 3y \)?

**Tip:** Always follow the order of operations (PEMDAS) when evaluating expressions involving more than one operation.

Find the value of:

a) 2x when x = 5
b) 4y when y = -3
c) 3z when z = 1.2

Learn how to evaluate simple algebraic expressions, such as 2x when x = 5, 4y when y = -3, and 3z when z = 1.2. This problem covers key algebra concepts suitable for students in Grades 6-8.
