Let's start by letting Juwan's number be represented by \( x \).
According to the problem, we can set up the following equation based on the information given:
\[ 2(x + 12) = 3x - 4 \]
Now, let's solve the equation step by step.
-
Distribute on the left side: \[ 2x + 24 = 3x - 4 \]
-
Next, we'll move the \( 2x \) to the right side of the equation: \[ 24 = 3x - 2x - 4 \] Simplifying, we get: \[ 24 = x - 4 \]
-
Now, add 4 to both sides: \[ 24 + 4 = x \] Simplifying, we find: \[ x = 28 \]
Therefore, Juwan is thinking of the number 28.
