Solving for the Value of m in a Linear Equation

Introduction

In algebra, solving for the value of a variable in a linear equation is a fundamental concept. A linear equation is an equation in which the highest power of the variable(s) is 1. In this article, we will focus on solving for the value of m in the equation 1/2m - 3/4n = 16, given that n = 8.

Understanding the Equation

The given equation is 1/2m - 3/4n = 16. To solve for the value of m, we need to isolate m on one side of the equation. The equation involves two variables, m and n, and their coefficients are fractions. We will use algebraic techniques to simplify the equation and solve for m.

Substituting the Value of n

We are given that n = 8. We can substitute this value into the equation to get:

1/2m - 3/4(8) = 16

Simplifying the Equation

To simplify the equation, we need to evaluate the expression 3/4(8). This is equal to 6. So, the equation becomes:

1/2m - 6 = 16

Isolating m

To isolate m, we need to get rid of the constant term -6. We can do this by adding 6 to both sides of the equation:

1/2m = 16 + 6

Evaluating the Right-Hand Side

The right-hand side of the equation is 16 + 6, which is equal to 22. So, the equation becomes:

1/2m = 22

Solving for m

To solve for m, we need to get rid of the coefficient 1/2. We can do this by multiplying both sides of the equation by 2:

m = 22(2)

Evaluating the Right-Hand Side

The right-hand side of the equation is 22(2), which is equal to 44. So, the value of m is 44.

Conclusion

In this article, we solved for the value of m in the equation 1/2m - 3/4n = 16, given that n = 8. We used algebraic techniques to simplify the equation and isolate m. The value of m is 44.

Final Answer

The final answer is 44.

Discussion

This problem is a classic example of solving for the value of a variable in a linear equation. The key concept is to isolate the variable on one side of the equation and get rid of the constant term. The solution involves simplifying the equation, evaluating expressions, and using algebraic techniques to solve for the value of m.
