Introduction

In this article, we will delve into the world of algebra and solve a complex equation involving variables x, y, and z. The given equation is xy + yz, with the additional constraints that xz = 2 and y = 5. We will break down the problem step by step, using algebraic manipulations to simplify the equation and ultimately find the solution.

Understanding the Given Constraints

Before we begin solving the equation, let's take a closer look at the given constraints. We are told that xz = 2 and y = 5. These constraints provide us with valuable information that we can use to simplify the equation.

The Constraint xz = 2

The constraint xz = 2 tells us that the product of x and z is equal to 2. This means that we can express z in terms of x as z = 2/x.

The Constraint y = 5

The constraint y = 5 tells us that the value of y is fixed at 5. This means that we can substitute y = 5 into the equation xy + yz to simplify it.

Substituting the Constraints into the Equation

Now that we have a better understanding of the given constraints, let's substitute them into the equation xy + yz.

Substituting y = 5 into the Equation

We can substitute y = 5 into the equation xy + yz to get:

5x + 5z

Substituting z = 2/x into the Equation

We can substitute z = 2/x into the equation 5x + 5z to get:

5x + 5(2/x)

Simplifying the Equation

Now that we have substituted the constraints into the equation, let's simplify it further.

Simplifying the Equation 5x + 10/x

We can simplify the equation 5x + 10/x by combining the terms:

(5x^2 + 10)/x

Factoring the Equation

We can factor the equation (5x^2 + 10)/x to get:

(5x^2 + 10)/x = 5x + 10/x

Solving for x

Now that we have simplified the equation, let's solve for x.

Setting the Equation Equal to 0

We can set the equation 5x + 10/x equal to 0 to get:

5x + 10/x = 0

Multiplying Both Sides by x

We can multiply both sides of the equation 5x + 10/x = 0 by x to get:

5x^2 + 10 = 0

Subtracting 10 from Both Sides

We can subtract 10 from both sides of the equation 5x^2 + 10 = 0 to get:

5x^2 = -10

Dividing Both Sides by 5

We can divide both sides of the equation 5x^2 = -10 by 5 to get:

x^2 = -2

Taking the Square Root of Both Sides

We can take the square root of both sides of the equation x^2 = -2 to get:

x = ±√(-2)

Simplifying the Square Root

We can simplify the square root √(-2) to get:

x = ±i√2

Conclusion

In this article, we have solved the equation xy + yz when xz = 2 and y = 5. We have used algebraic manipulations to simplify the equation and ultimately find the solution. The final solution is x = ±i√2.

Final Answer

The final answer is x = ±i√2.

Discussion

The equation xy + yz is a complex equation that involves variables x, y, and z. The given constraints xz = 2 and y = 5 provide valuable information that we can use to simplify the equation. By substituting the constraints into the equation and simplifying it further, we can solve for x.
