Introduction

Solving equations involving square roots can be a challenging task, especially when they involve variables. In this article, we will focus on solving the equation 8x4815=11\sqrt{8x - 48} - 15 = -11. This equation requires careful manipulation and application of algebraic techniques to isolate the variable xx. Our goal is to provide a step-by-step solution to this equation, making it easier for readers to understand and apply the concepts.

Understanding the Equation

The given equation is 8x4815=11\sqrt{8x - 48} - 15 = -11. To begin solving this equation, we need to isolate the square root term. We can do this by adding 15 to both sides of the equation, which gives us:

8x48=11+15\sqrt{8x - 48} = -11 + 15

8x48=4\sqrt{8x - 48} = 4

Simplifying the Equation

Now that we have isolated the square root term, we can simplify the equation by squaring both sides. This will help us eliminate the square root and make it easier to solve for xx. Squaring both sides of the equation gives us:

8x48=428x - 48 = 4^2

8x48=168x - 48 = 16

Solving for xx

Now that we have simplified the equation, we can solve for xx. To do this, we need to isolate the variable xx on one side of the equation. We can do this by adding 48 to both sides of the equation, which gives us:

8x=16+488x = 16 + 48

8x=648x = 64

Final Step

Now that we have isolated the variable xx, we can solve for its value. To do this, we need to divide both sides of the equation by 8, which gives us:

x=648x = \frac{64}{8}

x=8x = 8

Conclusion

In this article, we have solved the equation 8x4815=11\sqrt{8x - 48} - 15 = -11. We started by isolating the square root term, then simplified the equation by squaring both sides. Finally, we solved for the value of xx by isolating the variable on one side of the equation. The final solution is x=8x = 8. This equation requires careful manipulation and application of algebraic techniques to isolate the variable xx. Our goal is to provide a step-by-step solution to this equation, making it easier for readers to understand and apply the concepts.
