Introduction

In geometry, a parallelogram is a quadrilateral with opposite sides that are parallel to each other. One of the key properties of a parallelogram is that its diagonals bisect each other, meaning they intersect at a single point. In this article, we will explore a problem involving the diagonals of a parallelogram and use algebraic techniques to find the value of a variable.

The Problem

The diagonals of a parallelogram bisect each other at point "E." If $$AE = 4x - 3$$ and $$EC = 2x + 5$$, what is the value of $$x$$?

Understanding the Problem

To solve this problem, we need to understand the concept of bisecting diagonals and how they relate to the sides of a parallelogram. In a parallelogram, the diagonals intersect at a point that divides each diagonal into two equal parts. This means that the length of each diagonal is equal to the sum of the lengths of the two segments into which it is divided.

Setting Up the Equation

Since the diagonals bisect each other, we can set up an equation based on the fact that the sum of the lengths of the two segments of each diagonal is equal. Let's denote the point of intersection as "E." Then, we can write:

AE + EC = 2 \times AE

Substituting the given values, we get:

(4x - 3) + (2x + 5) = 2 \times (4x - 3)

Simplifying the Equation

Now, let's simplify the equation by combining like terms:

6x + 2 = 8x - 6

Solving for x

To solve for $$x$$, we need to isolate the variable on one side of the equation. Let's subtract $$6x$$ from both sides:

2 = 2x - 6

Next, let's add $$6$$ to both sides:

8 = 2x

Finally, let's divide both sides by $$2$$:

x = 4

Conclusion

In this article, we used algebraic techniques to solve a problem involving the diagonals of a parallelogram. We set up an equation based on the fact that the diagonals bisect each other and then simplified and solved for the variable $$x$$. The value of $$x$$ is $$4$$.
