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

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

• A. x = 3
• B. x = 5
• C. x = 10
• D. x = 7.5

Answer: (B)

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.

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.
