Certainly! Let's solve for $$ y $$ step by step by substituting $$ x = 3 $$ into the equation $$ y = 2 \cdot 3^{x} $$.

### Given:
$$ y = 2 \cdot 3^{x} $$
$$ x = 3 $$

### Step 1: Substitute $$ x = 3 $$ into the equation.
$$ y = 2 \cdot 3^{3} $$

### Step 2: Calculate $$ 3^{3} $$.
$$ 3^{3} = 3 \times 3 \times 3 = 27 $$

### Step 3: Multiply by 2 to find $$ y $$.
$$ y = 2 \times 27 $$
$$ y = 54 $$

### **Answer:**
$$ y = 54 $$
$$ y = 54 $$

If \( x=3 \), solve for \( y \) \[ y=2 \cdot 3^{x} \] First plug in the value of \( x \) into the equation. \[ y=2 \cdot 3[?] \]
