We are tasked with solving the equation:

[ \sqrt[3]{x + 7} - \sqrt[3]{2x - 1} = \sqrt[3]{x} ]

Step 1: Isolate one cube root term.

Move the term $\sqrt[3]{2x - 1}$ to the right-hand side of the equation:

[ \sqrt[3]{x + 7} = \sqrt[3]{x} + \sqrt[3]{2x - 1} ]

Step 2: Cube both sides to eliminate the cube roots.

Cubing both sides:

[ \left( \sqrt[3]{x + 7} \right)^3 = \left( \sqrt[3]{x} + \sqrt[3]{2x - 1} \right)^3 ]

This simplifies the left-hand side to $x + 7$, while for the right-hand side, we use the binomial expansion:

$(a + b)^3 = a^3 + 3a^2b + 3ab^2 + b^3$

where $a = \sqrt[3]{x}$ and $b = \sqrt[3]{2x - 1}$:

[ x + 7 = x + (2x - 1) + 3\sqrt[3]{x}\cdot\sqrt[3]{x}\cdot\sqrt[3]{2x - 1} ]

This simplifies to:

[ x + 7 = 3x - 1 + 3\sqrt[3]{x}\sqrt[3]{x(2x - 1)} ]

Step 3: Simplify the equation.

Now we have:

$x + 7 = 3x - 1 + 3\sqrt[3]{x^2(2x - 1)}$

Move the terms involving cube roots to one side and simplify the constants:

$8 = 2x + 3\sqrt[3]{x^2(2x - 1)}$

At this point, solving this equation analytically becomes more complex. The best approach is to use numerical methods or graphing to find approximate solutions.

Would you like me to continue solving this numerically, or would you like further clarification on any part of the process?
