Introduction

In this article, we will delve into solving a linear equation involving variables and constants. The equation is given as:

{ \begin{aligned} \frac{1}{2}(13x + 5x - 6 - 8x + 14) &= \frac{1}{2}(10x + 8) \\ &= \square x + \square \end{aligned} \}

Our goal is to simplify the equation and fill in the squares with the appropriate numbers to complete the equation.

Simplifying the Left Side of the Equation

To simplify the left side of the equation, we need to combine like terms. The equation contains several terms with the variable x and constants.

{ \begin{aligned} \frac{1}{2}(13x + 5x - 6 - 8x + 14) &= \frac{1}{2}(13x + 5x - 8x) - \frac{1}{2}(6 + 14) \\ &= \frac{1}{2}(10x) - \frac{1}{2}(20) \\ &= 5x - 10 \end{aligned} \}

Simplifying the Right Side of the Equation

The right side of the equation is already simplified, but we can rewrite it to make it easier to compare with the left side.

{ \begin{aligned} \frac{1}{2}(10x + 8) &= \frac{1}{2}(10x) + \frac{1}{2}(8) \\ &= 5x + 4 \end{aligned} \}

Equating the Two Sides of the Equation

Now that we have simplified both sides of the equation, we can equate them to solve for x.

{ \begin{aligned} 5x - 10 &= 5x + 4 \end{aligned} \}

Solving for x

To solve for x, we need to isolate the variable x on one side of the equation. We can do this by subtracting 5x from both sides of the equation.

{ \begin{aligned} 5x - 5x - 10 &= 5x - 5x + 4 \\ -10 &= 4 \end{aligned} \}

However, this is a contradiction, as -10 cannot equal 4. This means that the original equation has no solution.

Conclusion

In this article, we solved a linear equation involving variables and constants. We simplified both sides of the equation and equated them to solve for x. However, we found that the original equation has no solution, as the two sides of the equation are not equal.
