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 to3x = 15 - Divide both sides of the equation by 3 to solve for x:
x = 15 / 3
This simplifies tox = 5
Therefore, the value of x is 5.
