y = -3
Step-by-step explanation:
9x + 7y = -12
9(1) + 7y = -12

![{b}^{2} + 3b - 3 = 0](https://tex.z-dn.net/?f=%20%7Bb%7D%5E%7B2%7D%20%20%2B%203b%20-%203%20%3D%200)
Step-by-step explanation:
![{b}^{2} + 3b - 3 = 0 \\ because \: \: {b}^{2} < 4ac \\ {b}^{2} = {3}^{2} = 9 \\ 4ac = 4 \times 1 \times - 3 = - 12 \\ hence : {b}^{2} < 4ac](https://tex.z-dn.net/?f=%20%7Bb%7D%5E%7B2%7D%20%20%2B%203b%20-%203%20%3D%200%20%5C%5C%20because%20%5C%3A%20%20%5C%3A%20%20%7Bb%7D%5E%7B2%7D%20%20%3C%204ac%20%5C%5C%20%7Bb%7D%5E%7B2%7D%20%20%20%20%3D%20%7B3%7D%5E%7B2%7D%20%20%3D%209%20%5C%5C%204ac%20%3D%204%20%5Ctimes%201%20%5Ctimes%20%20-%203%20%3D%20%20-%2012%20%5C%5C%20hence%20%3A%20%20%7Bb%7D%5E%7B2%7D%20%20%3C%204ac)
