To solve the equation \( 4x - 9 = 19 \), follow these steps:

  1. Add 9 to both sides of the equation: \[ 4x - 9 + 9 = 19 + 9 \] This simplifies to: \[ 4x = 28 \]

  2. Now, divide both sides by 4: \[ x = \frac{28}{4} \] Simplifying the fraction gives: \[ x = 7 \]

Therefore, the value of \( x \) is \( 7 \).
