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.
- Distribute \( 2 \) on the left side:
\[ 2x + 24 = 3x - 4 \]
- Next, we'll isolate \( x \) by subtracting \( 2x \) from both sides:
\[ 24 = 3x - 2x - 4 \]
This simplifies to:
\[ 24 = x - 4 \]
- Now, add \( 4 \) to both sides to get \( x \):
\[ 24 + 4 = x \]
So,
\[ x = 28 \]
Thus, Juwan is thinking of the number 28.
