Which one shows an expression? * \( 2 a+3 b=24 \) \( 2+3 y \) \( 12+7 \times 5=47 \)

To determine which of the given options shows an expression, we need to understand the definitions: - An **expression** is a combination of numbers, variables, and operators (like addition, subtraction, multiplication, and division) that does not include an equality sign. - An **equation** is a statement that two expressions are equal, indicated by an equality sign (=). Now, let's analyze each option: 1. \( 2 a + 3 b = 24 \) - This is an equation because it has an equality sign. 2. \( 2 + 3 y \) - This is an expression because it does not have an equality sign. 3. \( 12 + 7 \times 5 = 47 \) - This is also an equation because it has an equality sign. Based on this analysis, the option that shows an expression is: **\( 2 + 3 y \)**.
