\[\begin{aligned}&8x\times 3+1-6-(-x)\\&8x-9-6\times 2+4\times -8\\&\frac{\frac{4}{9}}{\frac{2}{5}}+\frac{8}{9}\times \frac{2}{5}\end{aligned}\]
Simplify \(8x\times 3\) to \(24x\).
\[\begin{aligned}&24x+1-6-(-x)\\&8x-9-6\times 2+4\times -8\\&\frac{\frac{4}{9}}{\frac{2}{5}}+\frac{8}{9}\times \frac{2}{5}\end{aligned}\]
Simplify \(6\times 2\) to \(12\).
\[\begin{aligned}&24x+1-6-(-x)\\&8x-9-12+4\times -8\\&\frac{\frac{4}{9}}{\frac{2}{5}}+\frac{8}{9}\times \frac{2}{5}\end{aligned}\]
Use this rule: \(\frac{a}{b} \times \frac{c}{d}=\frac{ac}{bd}\).
\[\begin{aligned}&24x+1-6-(-x)\\&8x-9-12+4\times -8\\&\frac{\frac{4}{9}}{\frac{2}{5}}+\frac{8\times 2}{9\times 5}\end{aligned}\]
Simplify \(8\times 2\) to \(16\).
\[\begin{aligned}&24x+1-6-(-x)\\&8x-9-12+4\times -8\\&\frac{\frac{4}{9}}{\frac{2}{5}}+\frac{16}{9\times 5}\end{aligned}\]
Simplify \(9\times 5\) to \(45\).
\[\begin{aligned}&24x+1-6-(-x)\\&8x-9-12+4\times -8\\&\frac{\frac{4}{9}}{\frac{2}{5}}+\frac{16}{45}\end{aligned}\]
Remove parentheses.
\[\begin{aligned}&24x+1-6+x\\&8x-9-12+4\times -8\\&\frac{\frac{4}{9}}{\frac{2}{5}}+\frac{16}{45}\end{aligned}\]
24*x+1-6+x;8*x-9-12+4*-8;4/9/(2/5)+16/45
