Solving for y: A Step-by-Step Guide to Understanding the Equation y = ∛(x+1) - 4

In mathematics, solving for a variable is a crucial concept that helps us find the value of the variable in a given equation. In this article, we will focus on solving for y in the equation y = ∛(x+1) - 4. This equation involves a cube root, which can be a bit challenging to solve. However, with a step-by-step approach, we can break down the problem and find the value of y.

The given equation is y = ∛(x+1) - 4. To solve for y, we need to isolate y on one side of the equation. The equation involves a cube root, which means that we need to find the cube root of (x+1) and then subtract 4 from it.

Step 1: Isolate the Cube Root

The first step is to isolate the cube root on one side of the equation. We can do this by adding 4 to both sides of the equation. This will give us:

y + 4 = ∛(x+1)

Step 2: Remove the Cube Root

Now that we have isolated the cube root, we can remove it by cubing both sides of the equation. This will give us:

(y + 4)^3 = x + 1

Step 3: Expand the Left Side

To expand the left side of the equation, we need to use the formula (a + b)^3 = a^3 + 3a^2b + 3ab^2 + b^3. In this case, a = y + 4 and b = 0. However, since we are dealing with a cube root, we will use the formula (a + b)^3 = a^3 + 3a^2b + 3ab^2 + b^3, but we will not expand it fully.

(y + 4)^3 = (y + 4)(y + 4)(y + 4) = (y + 4)^3 = x + 1

Step 4: Simplify the Equation

Now that we have expanded the left side of the equation, we can simplify it by canceling out the cube root. This will give us:

y^3 + 12y^2 + 48y + 64 = x + 1

Step 5: Subtract x from Both Sides

To isolate y, we need to subtract x from both sides of the equation. This will give us:

y^3 + 12y^2 + 48y + 63 = 0

Step 6: Solve for y

Now that we have isolated y, we can solve for y by factoring the left side of the equation. However, this equation is a cubic equation, and factoring it can be challenging. In this case, we will use numerical methods to find the value of y.

Numerical Methods

To find the value of y, we can use numerical methods such as the Newton-Raphson method. This method involves making an initial guess for the value of y and then iteratively improving the guess until we converge to the correct value.

In this article, we have solved for y in the equation y = ∛(x+1) - 4. We have used a step-by-step approach to isolate y and then used numerical methods to find the value of y. The equation involves a cube root, which can be challenging to solve. However, with the right approach, we can break down the problem and find the value of y.

The final answer is not a simple number, but rather a function of x. The equation y = ∛(x+1) - 4 is a cubic equation, and the value of y depends on the value of x. However, we can use numerical methods to find the value of y for a given value of x.

Suppose we want to find the value of y when x = 2. We can plug x = 2 into the equation y = ∛(x+1) - 4 and solve for y.

y = ∛(2 + 1) - 4 y = ∛3 - 4 y ≈ 0.4422 - 4 y ≈ -3.5578

Therefore, when x = 2, the value of y is approximately -3.5578.

Here is a Python code implementation of the equation y = ∛(x+1) - 4:

import math

def solve_for_y(x):
    return math.pow((x + 1), 1/3) - 4

x = 2
y = solve_for_y(x)
print(y)

This code defines a function solve_for_y that takes x as input and returns the value of y. We can then call this function with x = 2 to find the value of y.
