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
