❌ Incorrect. Let's go through the steps to solve the equation.

The goal is to isolate $x$ .

Subtract 7 from both sides of the equation to get the term with $x$ by itself.
$3x + 7 - 7 = 19 - 7$ $3x = 12$
Divide both sides by 3 to solve for $x$ .
$\frac{3x}{3} = \frac{12}{3}$ $x = 4$
The correct answer is 4.
