Use elimination. Adding the two equations cancels y:
(2x + 3y) + (7x − 3y) = −5 + 23
9x = 18 → x = 2.
Substitute into 2x + 3y = −5:
4 + 3y = −5 → 3y = −9 → y = −3.
Solution: (x, y) = (2, −3).
(2x + 3y) + (7x − 3y) = −5 + 23
9x = 18 → x = 2.
Substitute into 2x + 3y = −5:
4 + 3y = −5 → 3y = −9 → y = −3.
Solution: (x, y) = (2, −3).
