Answer 1

1.

$y = x$

$x = y$

$y = x$

обратная функция

$y = x$

2.

$y = - 2 - 4$

$x = - 2y - 4$

$- 2y - 4 = x$

$- 2y = x + 4$

$y = - \frac{1}{2}x - 2$

3.

$y = 8 - x$

$x = 8 - y$

$8 - y = x$

$- y = x - 8$

$y = - x + 8$

4.

$y = 12 - 3x$

$x = 12 - 3y$

$12 - 3y = x$

$- 3y = x - 12$

$y = - \frac{1}{3}x + 4$
