Solve for x in the equation: 2x + 5 = 15.

To solve the equation 2x + 5 = 15, the goal is to isolate x on one side of the equation.

First, subtract 5 from both sides of the equation to eliminate the constant term on the left:

2x + 5 - 5 = 15 - 5

This simplifies to:

2x = 10

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

2x / 2 = 10 / 2

This results in:

x = 5

Thus, the solution to the equation is x = 5. This matches option B, making it the correct answer. The arithmetic steps confirm that by following the proper order of operations, we arrive at the correct value of x.
