What is the value of y in the equation: 2y - 7 = 13?

To find the value of y in the equation 2y - 7 = 13, the first step is to isolate the term containing y on one side of the equation. Start by adding 7 to both sides to eliminate the -7:

2y - 7 + 7 = 13 + 7

This simplifies to:

2y = 20

Next, to solve for y, divide both sides of the equation by 2:

2y / 2 = 20 / 2

This results in:

y = 10

Thus, the value of y that satisfies the equation 2y - 7 = 13 is 10. Understanding how to isolate variables and perform basic algebraic operations is crucial in solving equations like this one.
