Introduction

In mathematics, equations are used to represent relationships between variables. One of the fundamental concepts in algebra is solving linear equations, which involve variables and constants. In this article, we will explore the difference of 100 and x, represented by the equation 100−x=57.1100 - x = 57.1. We will examine four different equations and determine which one is correct.

Equation 1: 100−x=57.1100 - x = 57.1

The first equation is 100−x=57.1100 - x = 57.1. This equation states that the difference between 100 and x is equal to 57.1. To solve for x, we need to isolate the variable x. We can do this by subtracting 100 from both sides of the equation.

100 - x = 57.1
-x = 57.1 - 100
-x = -42.9
x = 42.9

Equation 2: x+100=57x + 100 = 57

The second equation is x+100=57x + 100 = 57. This equation states that x plus 100 is equal to 57. To solve for x, we need to isolate the variable x. We can do this by subtracting 100 from both sides of the equation.

x + 100 = 57
x = 57 - 100
x = -43

Equation 3: x−100=57x - 100 = 57

The third equation is x−100=57x - 100 = 57. This equation states that x minus 100 is equal to 57. To solve for x, we need to isolate the variable x. We can do this by adding 100 to both sides of the equation.

x - 100 = 57
x = 57 + 100
x = 157

Equation 4: 100−57=x100 - 57 = x

The fourth equation is 100−57=x100 - 57 = x. This equation states that the difference between 100 and 57 is equal to x. To solve for x, we can simply calculate the difference.

100 - 57 = x
x = 43

Conclusion

In conclusion, we have examined four different equations and determined which one is correct. The correct equation is 100−x=57.1100 - x = 57.1, which states that the difference between 100 and x is equal to 57.1. Solving for x, we get x = 42.9.
