Question
$$9x(\frac{15}{4}-4)^3-10 = 0$$
Answer
This equation has no solution.
Explanation
$$ \begin{aligned} 9x(\frac{15}{4}-4)^3-10 &= 0&& \text{multiply ALL terms by } \color{blue}{ 4 }. \\[1 em]49x(\frac{15}{4}-4)^3-4\cdot10 &= 4\cdot0&& \text{cancel out the denominators} \\[1 em]0-40 &= 0&& \text{simplify left side} \\[1 em]-40 &= 0&& \\[1 em] \end{aligned} $$
Since the statement $ \color{red}{ -40 = 0 } $ is FALSE, we conclude that the equation has no solution.
