The Correct Option is B

Solution and Explanation

To find the value of x in the equation 3x + 4 = 19, follow these steps:

  • Subtract 4 from both sides of the equation to isolate the term with x:
    3x + 4 - 4 = 19 - 4
    This simplifies to
    3x = 15
  • Divide both sides of the equation by 3 to solve for x:
    x = 15 / 3
    This simplifies to
    x = 5

Therefore, the value of x is 5.
