Given x = 3y + 17, substitute into 3x + 4y = -14:
3(3y + 17) + 4y = -14
9y + 51 + 4y = -14
13y + 51 = -14
13y = -65
y = -5
Then x = 3(-5) + 17 = 2.
Solution: (x, y) = (2, -5).
3(3y + 17) + 4y = -14
9y + 51 + 4y = -14
13y + 51 = -14
13y = -65
y = -5
Then x = 3(-5) + 17 = 2.
Solution: (x, y) = (2, -5).
