Помогите решить уровнение
4x-8y=36

Answer 1

$4x - 8y = 36 \\ \\ \\ x - 2y = 9 \\ \\ \\ x = 9 + 2y.$

$4x - 8y = 36 \\ \\ \\ \frac{4x}{4} - \frac{8y}{4} = \frac{36}{4} \\ \\ \\ x - 2y = 9 \\ \\ \\ - 2y = 9 - x \\ \\ \\ 2y = - 9 + x \\ \\ \\ 2y = x - 9 \\ \\ \\ y = \frac{x}{2} - \frac{9}{2} \\ \\ y = 0.5x - 4.5$
