Answer 1

Вы решили систему уравнений методом сложения. Ваши решения верны. Вот их суммарно:

1. $m = -2, n = 4$
2. $x = 5, y = 1$
3. $x = 4, y = -3$
4. $x = 0.5, y = -0.5$

Все решения были получены верно, и вы использовали метод сложения для решения каждой системы. Если у вас есть ещё какие-либо вопросы, не стесняйтесь спрашивать!
