$$

Introduction

Solving equations involving square roots can be a challenging task, especially when the equations are not straightforward. In this article, we will focus on solving the equation $\sqrt{5x + 3} = \sqrt{4x + 5}$, which involves square roots on both sides. We will use algebraic techniques to simplify the equation and find the solution.

Understanding the Equation

The given equation is $\sqrt{5x + 3} = \sqrt{4x + 5}$. This equation involves two square roots, one on the left-hand side and one on the right-hand side. To solve this equation, we need to eliminate the square roots and find the value of $x$.

Step 1: Square Both Sides

One of the most common techniques for solving equations involving square roots is to square both sides of the equation. This will eliminate the square roots and allow us to simplify the equation.

\sqrt{5x + 3} = \sqrt{4x + 5}

Squaring both sides of the equation, we get:

(\sqrt{5x + 3})^2 = (\sqrt{4x + 5})^2

Using the property of exponents, we can simplify the equation as follows:

5x + 3 = 4x + 5

Step 2: Simplify the Equation

Now that we have squared both sides of the equation, we can simplify the equation further. We can start by subtracting $4x$ from both sides of the equation:

5x - 4x + 3 = 4x - 4x + 5

This simplifies to:

x + 3 = 5

Step 3: Solve for $x$

Now that we have simplified the equation, we can solve for $x$. We can start by subtracting $3$ from both sides of the equation:

x + 3 - 3 = 5 - 3

This simplifies to:

x = 2

Conclusion

In this article, we have solved the equation $\sqrt{5x + 3} = \sqrt{4x + 5}$ using algebraic techniques. We started by squaring both sides of the equation, which eliminated the square roots and allowed us to simplify the equation. We then simplified the equation further and solved for $x$. The final solution is $x = 2$.
