Introduction

When working with equations, it's essential to understand the impact of operations on the variables and constants involved. In this case, we're given an equation $4x = 3x$ and asked to consider what happens when 2 is added to both sides. This seemingly simple operation can have significant effects on the solution set of the equation. In this article, we'll explore the implications of adding 2 to both sides and determine which solution best illustrates the outcome.

The Original Equation

The original equation is $4x = 3x$ . This equation is a linear equation in one variable, $x$ . To solve for $x$ , we can use basic algebraic manipulations. However, before we proceed, let's examine the equation and understand its properties.

4x = 3x

Adding 2 to Both Sides

When we add 2 to both sides of the equation, we get:

4x + 2 = 3x + 2

This new equation is also a linear equation in one variable, $x$ . However, the addition of 2 to both sides has changed the equation's properties. Let's analyze the new equation and determine its solution set.

Solution Set Analysis

To find the solution set of the new equation, we can subtract 3x from both sides:

4x - 3x + 2 = 3x - 3x + 2
x + 2 = 2

Next, we can subtract 2 from both sides:

x + 2 - 2 = 2 - 2
x = 0

This result indicates that the new equation has a single solution, $x = 0$ . However, we must consider the implications of adding 2 to both sides on the original equation's solution set.

Implications of Adding 2 to Both Sides

When we add 2 to both sides of the original equation, we are essentially changing the equation's properties. The addition of 2 to both sides does not affect the solution set of the original equation. In other words, the solution set of the original equation remains unchanged.

However, the new equation $x + 2 = 2$ has a single solution, $x = 0$ . This result may seem counterintuitive, as we would expect the solution set of the new equation to be the same as the original equation. But, as we'll discuss later, this is not the case.

Solution Set of the Original Equation

The original equation $4x = 3x$ has an infinite solution set. This is because the equation is true for all values of $x$ . In other words, no matter what value we assign to $x$ , the equation will always be true.

4x = 3x
4x - 3x = 3x - 3x
x = 0

However, as we've seen, adding 2 to both sides of the equation results in a new equation with a single solution, $x = 0$ . This highlights the importance of understanding the impact of operations on the variables and constants involved in an equation.

Conclusion

In conclusion, when we add 2 to both sides of the equation $4x = 3x$ , we get a new equation with a single solution, $x = 0$ . However, the solution set of the original equation remains unchanged. This result illustrates the importance of understanding the implications of operations on the variables and constants involved in an equation.

Final Thoughts

When working with equations, it's essential to consider the impact of operations on the solution set. In this case, adding 2 to both sides of the equation resulted in a new equation with a single solution. However, the solution set of the original equation remained unchanged. This highlights the importance of understanding the properties of equations and the implications of operations on the variables and constants involved.
