Solution Steps

Solution Approach

To solve a two-step equation, you typically need to perform two inverse operations to isolate the variable. First, undo any addition or subtraction, and then undo any multiplication or division.

Step 1: Set Up the Equation

We start with the equation: \[ 3x + 4 = 19 \]

Step 2: Isolate the Variable

To isolate \( x \), we first subtract \( 4 \) from both sides: \[ 3x + 4 - 4 = 19 - 4 \] This simplifies to: \[ 3x = 15 \]

Step 3: Solve for \( x \)

Next, we divide both sides by \( 3 \): \[ \frac{3x}{3} = \frac{15}{3} \] This gives us: \[ x = 5 \]

Final Answer

\(\boxed{x = 5}\)
