Introduction

Solving for x is a fundamental concept in mathematics that involves finding the value of a variable in an equation. In this article, we will explore three different conditions and determine the value of x based on each condition. We will also discuss the importance of solving for x and its applications in various fields.

Condition 1: $x = 10$

The first condition states that x is equal to 10. This means that the value of x is a constant, and we can substitute 10 for x in any equation. For example, if we have the equation 2x + 5 = 21, we can substitute 10 for x and solve for the value of the equation.

# Define the equation
def equation(x):
    return 2*x + 5

# Substitute 10 for x
result = equation(10)

# Print the result
print(result)  # Output: 25

In this example, we defined a function called equation that takes x as an input and returns the value of the equation. We then substituted 10 for x and called the function to get the result. The result is 25, which is the value of the equation when x is equal to 10.

Condition 2: $x = -10$

The second condition states that x is equal to -10. This means that the value of x is a negative constant, and we can substitute -10 for x in any equation. For example, if we have the equation 3x - 2 = 26, we can substitute -10 for x and solve for the value of the equation.

# Define the equation
def equation(x):
    return 3*x - 2

# Substitute -10 for x
result = equation(-10)

# Print the result
print(result)  # Output: 28

In this example, we defined a function called equation that takes x as an input and returns the value of the equation. We then substituted -10 for x and called the function to get the result. The result is 28, which is the value of the equation when x is equal to -10.

Condition 3: $2.4 \times 4 = 9.6$

The third condition states that 2.4 multiplied by 4 is equal to 9.6. This means that we can use this condition to solve for x in an equation. For example, if we have the equation 2x = 9.6, we can use the condition to find the value of x.

# Define the equation
def equation(x):
    return 2*x

# Use the condition to solve for x
result = 9.6 / 2

# Print the result
print(result)  # Output: 4.8

In this example, we defined a function called equation that takes x as an input and returns the value of the equation. We then used the condition to solve for x by dividing 9.6 by 2. The result is 4.8, which is the value of x.
