Introduction

In mathematics, solving for a variable means finding the value of that variable that makes the equation true. In this article, we will focus on solving for z in the equation 1 = z/5. This equation is a simple linear equation, and we will use algebraic methods to solve for z.

Understanding the Equation

The equation 1 = z/5 is a simple linear equation. It states that the value of z divided by 5 is equal to 1. To solve for z, we need to isolate the variable z on one side of the equation.

Isolating the Variable

To isolate the variable z, we can multiply both sides of the equation by 5. This will cancel out the division by 5 on the left-hand side of the equation.

Multiplying Both Sides by 5

1 = z/5
5 * 1 = 5 * (z/5)
5 = z

Solving for z

Now that we have isolated the variable z, we can see that z is equal to 5. This is the solution to the equation 1 = z/5.

Conclusion

Solving for z in the equation 1 = z/5 is a simple process that involves isolating the variable z using algebraic methods. By multiplying both sides of the equation by 5, we can cancel out the division by 5 and solve for z. The solution to the equation is z = 5.

Example Use Cases

Solving for z in the equation 1 = z/5 has many practical applications in mathematics and real-world problems. Here are a few examples:

Finance: In finance, solving for z can help us calculate the value of an investment or a loan. For example, if we know that the interest rate on a loan is 5% and the loan amount is $100, we can use the equation 1 = z/5 to calculate the value of z, which represents the total amount paid back to the lender.
Science: In science, solving for z can help us calculate the value of a physical quantity, such as the speed of an object or the distance between two points. For example, if we know that the speed of an object is 5 meters per second and the time it takes to travel a certain distance is 1 second, we can use the equation 1 = z/5 to calculate the value of z, which represents the distance traveled.
Engineering: In engineering, solving for z can help us design and optimize systems, such as electrical circuits or mechanical systems. For example, if we know that the resistance of a circuit is 5 ohms and the voltage across the circuit is 1 volt, we can use the equation 1 = z/5 to calculate the value of z, which represents the current flowing through the circuit.
