Để tìm giá trị của x, ta cần giải phương trình sau đây:

\(\frac{5}{6} - \frac{7}{8} \div x = \frac{8}{9}\)

Đầu tiên, ta tính phép chia \(\frac{7}{8} \div x\):

\(\frac{7}{8} \div x = \frac{7}{8} \times \frac{1}{x} = \frac{7}{8x}\)

Sau đó, thay vào phương trình ban đầu:

\(\frac{5}{6} - \frac{7}{8x} = \frac{8}{9}\)

Đưa cả hai phân số về cùng mẫu số:

\(\frac{40x}{6x} - \frac{42}{8x} = \frac{48}{9}\)

\(\frac{40x}{6x} - \frac{42}{8x} = \frac{48}{9}\)

\(\frac{40x}{6x} - \frac{42}{8x} = \frac{48}{9}\)

\( \frac{20}{3} - \frac{21}{4} = \frac{16}{3}\)

\( \frac{80 - 63}{12} = \frac{16}{3}\)

\( \frac{17}{12} = \frac{16}{3}\)

\( \frac{17}{12} = \frac{16}{3}\)
