What is the value of x in the equation 2x + 5 = 15?

To find the value of x in the equation 2x + 5 = 15, we start by isolating x. First, subtract 5 from both sides of the equation:

2x + 5 - 5 = 15 - 5,

which simplifies to:

2x = 10.

Next, to solve for x, divide both sides by 2:

2x / 2 = 10 / 2,

leading to:

x = 5.

This solution shows that the correct answer is x = 5. Solving for x involves basic algebraic manipulation, and following the correct steps leads to the value of 5, which is confirmed by substitution back into the original equation.
