Introduction

In mathematics, equations are a fundamental concept that helps us solve problems and understand various mathematical relationships. When we encounter an equation like $z - 0 = 15$ , our goal is to find the value of the variable $z$ that satisfies the equation. In this article, we will explore the solution of this equation and provide a step-by-step guide on how to solve it.

Understanding the Equation

The given equation is $z - 0 = 15$ . To solve this equation, we need to isolate the variable $z$ on one side of the equation. The equation can be rewritten as $z = 15$ , where $0$ is the additive identity, meaning that when added to any number, it does not change the value of the number.

Solving the Equation

To solve the equation $z - 0 = 15$ , we can use the following steps:

Add 0 to both sides of the equation: This will not change the value of the equation, but it will help us isolate the variable $z$ .
Simplify the equation: After adding 0 to both sides, the equation becomes $z = 15$ .
Write the solution: The solution to the equation is $z = 15$ .

Why is the Solution $z = 15$ ?

The solution $z = 15$ is the value of the variable $z$ that satisfies the equation $z - 0 = 15$ . When we substitute $z = 15$ into the equation, we get:

$15 - 0 = 15$

This equation is true, which means that $z = 15$ is the correct solution to the equation.

What if the Equation is $z - 0 = -15$ ?

If the equation is $z - 0 = -15$ , we can follow the same steps to solve it:

Add 0 to both sides of the equation: This will not change the value of the equation, but it will help us isolate the variable $z$ .
Simplify the equation: After adding 0 to both sides, the equation becomes $z = -15$ .
Write the solution: The solution to the equation is $z = -15$ .

Conclusion

In conclusion, the solution to the equation $z - 0 = 15$ is $z = 15$ . We can solve this equation by adding 0 to both sides and simplifying the equation. The solution $z = 15$ satisfies the equation, and we can verify this by substituting $z = 15$ into the equation.
