Solve 5x<24 when `xinN`

Text Solution

AI Generated Solution

The correct Answer is:
To solve the inequality \( 5x < 24 \) where \( x \) belongs to the set of natural numbers, follow these steps: ### Step 1: Write the inequality We start with the given inequality: \[ 5x < 24 \] ### Step 2: Divide both sides by 5 To isolate \( x \), we divide both sides of the inequality by 5: \[ x < \frac{24}{5} \] ### Step 3: Simplify the fraction Now, we simplify \( \frac{24}{5} \): \[ \frac{24}{5} = 4.8 \] So, we have: \[ x < 4.8 \] ### Step 4: Identify natural numbers less than 4.8 The natural numbers are defined as the positive integers: \( 1, 2, 3, 4, 5, \ldots \) Since \( x \) must be a natural number and also less than 4.8, we list the natural numbers less than 4.8: - The natural numbers are \( 1, 2, 3, 4 \) ### Step 5: Write the solution Thus, the solution set for \( x \) in natural numbers is: \[ x \in \{ 1, 2, 3, 4 \} \] ### Final Answer: The natural numbers satisfying the inequality \( 5x < 24 \) are \( 1, 2, 3, \) and \( 4 \). ---
