Let's denote Juwan's number as \( x \). According to the problem, we can set up the following equation:

\[ 2(x + 12) = 3x - 4 \]

Now, let's solve this equation step by step.

  1. Distribute \( 2 \) on the left side:

\[ 2x + 24 = 3x - 4 \]

  1. Next, we'll isolate \( x \) by subtracting \( 2x \) from both sides:

\[ 24 = 3x - 2x - 4 \]

This simplifies to:

\[ 24 = x - 4 \]

  1. Now, add \( 4 \) to both sides to get \( x \):

\[ 24 + 4 = x \]

So,

\[ x = 28 \]

Thus, Juwan is thinking of the number 28.
