Find the point at which the tangent to the curve `y=(3)/(5)x^(5)-(5)/(3)x^(3)-x` has its slope equal to -3

Explanation

To find the point at which the tangent to the curve \( y = \frac{3}{5}x^5 - \frac{5}{3}x^3 - x \) has a slope equal to -3, we will follow these steps:

### Step 1: Find the derivative of the function
To find the slope of the tangent line, we need to compute the derivative \( \frac{dy}{dx} \).

\[ y = \frac{3}{5}x^5 - \frac{5}{3}x^3 - x \]
