Question
$$8-3\cdot(3-2)\cdot5-7+4\cdot\frac{4}{2} = 0$$
Answer
This equation has no solution.
Explanation
$$ \begin{aligned} 8-3\cdot(3-2)\cdot5-7+4\cdot\frac{4}{2} &= 0&& \text{multiply ALL terms by } \color{blue}{ 2 }. \\[1 em]2\cdot8-23\cdot(3-2)\cdot5-2\cdot7+2\cdot4\cdot\frac{4}{2} &= 2\cdot0&& \text{cancel out the denominators} \\[1 em]16-30-14+16 &= 0&& \text{simplify left side} \\[1 em]-12 &= 0&& \\[1 em] \end{aligned} $$
Since the statement $ \color{red}{ -12 = 0 } $ is FALSE, we conclude that the equation has no solution.
