Question

помогите мне пожалуйста​

Answer 1

Объяснение:

$- 3x + 2y = 2 \\ 3x - 3y = - 3$

$- y = - 1 \\ 3x = 3y - 3$

$y = 1 \\ x = \frac{3y - 3}{3}$

$y = 1 \\ x = 0$

$- 4p - 2k = 5 \\ 5p + 4k = 2$

$- 8p - 4k = 10 \\ 5p + 4k = 2$

$- 3p = 12 \\ - 4p - 2k = 5$

$p = - 4 \\ k = \frac{ - 4p - 5}{2}$

$p = - 4 \\ k = 5.5$

$4x + 2y = 14 \\ 3x + 9y = 33$

$- 12x - 6y = - 42 \\ 12x + 36y = 132$

$30y = 90 \\ 4x + 2y = 14$

$y = 3 \\ x = \frac{14 - 2y}{4}$

$y = 3 \\ x = 2$
