1 answer

Sure! Here’s a different procedure to solve for \( x \) in the equation \( 12x = 144 \).

Procedure using division:

  1. Start with the original equation: \[ 12x = 144 \]

  2. Instead of isolating \( x \) by dividing both sides by 12, we can divide both sides by \( x \): \[ 12 = \frac{144}{x} \]

  3. Now, to isolate \( x \), multiply both sides by \( x \): \[ 12x = 144 \]

  4. Now, divide both sides by 12: \[ x = \frac{144}{12} \]

  5. Simplify the right side: \[ x = 12 \]

So, the solution is: \[ x = 12 \]
