Solve for y: 2y + 5 = 25. What is the value of y?

y = 25
y = 100
y = 150
y = 200

The correct answer is: y = 100

To solve the equation $2y + 5 = 25$, the first step is to isolate the term containing $y$. Start by subtracting 5 from both sides of the equation: \[ 2y + 5 - 5 = 25 - 5 \] This simplifies to: \[ 2y = 20 \] Next, to solve for $y$, divide both sides by 2: \[ y = \frac{20}{2} \] This results in: \[ y = 10 \] However, the answer provided for $y = 100$ does not match the value derived from correctly solving the equation. The correct value of $y$ is actually 10, which should reflect on the choices provided. Thus, it’s important when solving equations to ensure that each step is followed accurately to arrive at the correct result.
