{x - 1 = 2(y + 6)

{x + 6 = 3(1 - 2y )

▪x - 1 = 2(y + 6)

x - 1 = 2y + 12

x - 2y = 12 + 1

x - 2y = 13

x = 13 + 2y

▪x + 6 = 3(1 - 2y )

x + 6 = 3 - 6y

x - 6y = 3 - 6

x - 6y = - 3

(13 + 2y) - 6y = - 3

13 + 2y - 6y = - 3 - 4y = - 3 - 13 - 4y = - 16

y = - 16 / - 4

y = 4

■x = 13 + 2y

x = 13 + 2 (4)

x = 13 + 8

x = 21.
