Ini jawabannya sama caranya gimana ya? Pliss bantu jawab

[tex]6. \: \frac{ {x}^{2} - 4x }{ {x}^{2} - 2x - 8 } = ... \\ \\ = \frac{x(x - 4)}{(x - 4)(x + 2)} \\ \\ = \frac{x}{x + 2} [/tex]

6. Jawaban A

[tex]7. \: \frac{2}{3} x + 2 = \frac{1}{4} x + 3 \\ \\ x + 3 = ... \\ \\ \frac{2}{3} x + 2 = \frac{1}{4} x + 3...( \times 12) \\ \\ 8x + 24 = 3x + 36 \\ 5x = 12 \\ \\ x = \frac{12}{5} \\ \\ x + 3 = ... \\ = \frac{12}{5} + 3 \\ \\ = \frac{12}{5} + \frac{15}{5} \\ \\ = \frac{27}{5} \\ \\ = 5 \frac{2}{5} \\ \\ = 5.4[/tex]
