Resuelve los siguientes sistemas de ecuaciones lineales utilizando el método de sustitución (verifica tu respuesta)

1) x + 2y = –1

2x + y = 4

2) 3x + y = –17

2x – 3y = 7

3) 3x + 2y = 14

x – 2y = 2

4) 2x – 3y = 8

9y – 6x = –2

5) 7x + 2y = –5

5y – 7x = 12

6) 2x – 3y = 13.8

5x + 2y = 6

7) 6x + 5y – 7 = 0

3 + 7y + 2x = 0

8) 5x + 4y = 4

3x – 2y = –8.6
