![{5}^{2} - 3[5] + 5 = h(5) → 25 - 15 + 5 = h(5) → 15 = h(5) \\ \\ [-3]^{2} - 3[-3] + 5 = h(-3) → 9 + 9 + 5 = h(-3) → 23 = h(-3)](https://tex.z-dn.net/?f=%7B5%7D%5E%7B2%7D%20-%203%5B5%5D%20%2B%205%20%3D%20h%285%29%20%E2%86%92%2025%20-%2015%20%2B%205%20%3D%20h%285%29%20%E2%86%92%2015%20%3D%20h%285%29%20%5C%5C%20%5C%5C%20%5B-3%5D%5E%7B2%7D%20-%203%5B-3%5D%20%2B%205%20%3D%20h%28-3%29%20%E2%86%92%209%20%2B%209%20%2B%205%20%3D%20h%28-3%29%20%E2%86%92%2023%20%3D%20h%28-3%29)
I am joyous to assist you.
4x+6y=8
3x+y=9
y = 9 - 3x
4x + 6( 9-3x ) = 8
4x + 54 - 18x = 8
14x = 46
x = 23/7
y = 9 - 3(23/7)
y = 9 - 69/7
y = - 6/7
