From the first equation, y = 12 + 9x. Substitute into the second:
2x + 4(12 + 9x) = −28
2x + 48 + 36x = −28
38x = −76 → x = −2.
Then y = 12 + 9(−2) = −6.
Solution: (x, y) = (−2, −6).
2x + 4(12 + 9x) = −28
2x + 48 + 36x = −28
38x = −76 → x = −2.
Then y = 12 + 9(−2) = −6.
Solution: (x, y) = (−2, −6).
