A + (-3) (b)

6x – 2y + ƶ = 24 -6x – 15y + 6 ƶ= 42 0- 17y + 7 ƶ = 66

Y= 66- 7 ƶ 17

A + (-6) (c)

6x – 2y + ƶ = 24 -6x + 24y - 18 ƶ = -156 0+ 22y - 17 ƶ = -132

22(66- 7 ƶ) = 17(-132 + 17 ƶ)

1452 -154 ƶ = -2244+289 ƶ 1452 + 2244 = 289 ƶ + 154 ƶ 3696 = 443 ƶ

Ƶ= 3696 = 8,4 443

Y= 17 ƶ – 132 22

Y= 17(8,4) – 132 22

Y= 142,8 – 132 22

Y= 10,8 = 0,5 22

X – 4y + 3 ƶ = 26

X – 4 (0,5) + 3 (8,4) = 26 X – 2 + 25,2 = 26 X= 26 – 23,2 X= 2,8

Prueba

X – 4y + 3 ƶ = 26

2,8 – 4 (0,5) + 3 (8,4) = 26 2,8 – 2 + 25,2 = 26 2,8 + 23,2 = 26 26=26
