Answer 1

(- 21, - 13 )

Explanation:

- 3y + x = 18 → (1)

x = 2y + 5 → (2)

substitute x = 2y + 5 into (1)

- 3y + 2y + 5 = 18

- y + 5 = 18 ( subtract 5 from both sides )

- y = 13 ( multiply both sides by - 1 )

y = 13

substitute y = - 13 into (2)

x = 2(- 13) + 5 = - 26 + 5 = - 21

solution is (- 21, - 13 )
