To find the value of ( x ) in the equation ( 3x + 7 = 16 ), we begin by isolating ( x ). First, we can eliminate the constant term on the left side by subtracting 7 from both sides of the equation:

[

3x + 7 - 7 = 16 - 7

]

which simplifies to:

[

3x = 9

]

Next, we need to resolve for ( x ) by dividing both sides of the equation by 3:

[

x = \frac{9}{3}

]

This simplifies to:

[

x = 3

]

Thus, the value of ( x ) is indeed 3, confirming that this answer is correct. This aligns with the goal of solving for ( x ) step by step through clear algebraic manipulation.
