Introduction

Linear equations are a fundamental concept in mathematics, and solving them is a crucial skill for students and professionals alike. In this article, we will focus on solving a linear equation using the given formula k=17d−19k = 17d - 19, where we need to find the value of kk when d=6d = 6. We will break down the solution into simple steps, making it easy to understand and follow.

Understanding the Equation

The given equation is k=17d−19k = 17d - 19. This is a linear equation in one variable, where kk is the dependent variable and dd is the independent variable. The equation represents a straight line, and the value of kk depends on the value of dd.

Substituting the Value of dd

To find the value of kk, we need to substitute the value of dd into the equation. In this case, we are given that d=6d = 6. We will substitute this value into the equation and solve for kk.

Step 1: Substitute the Value of dd

k=17d−19k = 17d - 19 k=17(6)−19k = 17(6) - 19

Step 2: Multiply 17 and 6

17(6)=10217(6) = 102

Step 3: Substitute the Result into the Equation

k=102−19k = 102 - 19

Step 4: Subtract 19 from 102

k=83k = 83

Conclusion

In this article, we used the equation k=17d−19k = 17d - 19 to find the value of kk when d=6d = 6. We broke down the solution into simple steps, making it easy to understand and follow. By substituting the value of dd into the equation and solving for kk, we found that k=83k = 83. This demonstrates the importance of following the order of operations and using the correct mathematical procedures to solve linear equations.
