Langkah 1.3.1

Kurangi $9 x$ dengan $3 x$ .

$\frac{- 6 x - 5 + 6}{x - 6} = \frac{1 - 6 x}{x - 6}$

Langkah 1.3.2

Tambahkan $- 5$ dan $6$ .

$\frac{- 6 x + 1}{x - 6} = \frac{1 - 6 x}{x - 6}$

Langkah 1.3.3

Faktorkan $- 1$ dari $- 6 x$ .

$\frac{- (6 x) + 1}{x - 6} = \frac{1 - 6 x}{x - 6}$

Langkah 1.3.4

Tulis kembali $1$ sebagai $- 1 (- 1)$ .

$\frac{- (6 x) - 1 (- 1)}{x - 6} = \frac{1 - 6 x}{x - 6}$

Langkah 1.3.5

Faktorkan $- 1$ dari $- (6 x) - 1 (- 1)$ .

$\frac{- (6 x - 1)}{x - 6} = \frac{1 - 6 x}{x - 6}$

Langkah 1.3.6

Sederhanakan pernyataannya.

Ketuk untuk lebih banyak langkah...

Langkah 1.3.6.1

Tulis kembali $- (6 x - 1)$ sebagai $- 1 (6 x - 1)$ .

$\frac{- 1 (6 x - 1)}{x - 6} = \frac{1 - 6 x}{x - 6}$

Langkah 1.3.6.2

Pindahkan tanda negatif di depan pecahan.

$- \frac{6 x - 1}{x - 6} = \frac{1 - 6 x}{x - 6}$

Langkah 2

Gambarkan setiap sisi persamaan. Penyelesaiannya adalah nilai x dari titik perpotongan.

$x \approx - 49.8, - 49.7, - 49.5, - 49.4, - 49.2, - 49.1, - 49, - 48.9, - 48.7, - 48.6, - 48.5, - 48.3, - 48.2, - 48.1, - 48, - 47.9, - 47.8, - 47.7, - 47.5, - 47.4, - 47.3, - 47.1, - 47, - 46.9, - 46.8, -
