1. \( 2 \times 7 > b \) 2. \( \frac{12}{3} = 4 \) 3. \( \frac{20}{a} = 4 \) 4. \( 16 < y < 8 \) 5. \( 3 \times x = 15 \)

Let's analyze each of these inequalities and equations step by step.

1. Inequality: \( 2 \times 7 > b \)

   Simplifying the left side gives us: \[ 14 > b \quad \text{or} \quad b < 14 \]

2. Equation: \( \frac{12}{3} = 4 \)

   This is a straightforward equation that is true: \[ 4 = 4 \quad \text{(Verified)} \]

3. Equation: \( \frac{20}{a} = 4 \)

   To solve for \( a \), we can multiply both sides by \( a \) (assuming \( a \neq 0 \)): \[ 20 = 4a \] Now divide both sides by 4: \[ a = \frac{20}{4} = 5 \]

4. Inequality: \( 16 < y < 8 \)

   This statement has no solution because the left side \( 16 \) is greater than the right side \( 8 \). The inequality cannot be satisfied, so: \[ \text{No solution for } y. \]

5. Equation: \( 3 \times x = 15 \)

   To solve for \( x \), divide both sides by 3: \[ x = \frac{15}{3} = 5 \]

Summary of Results:

• From (1): \( b < 14 \)
• From (2): True statement
• From (3): \( a = 5 \)
• From (4): No solution for \( y \)
• From (5): \( x = 5 \)
