-17
Step-by-step explanation:
Hello,
![y+5x^2=3\\\\ y=3-5x^2 =f(x)\\\\\text{So, }f(x)=3-5x^2\\\\f(2)=3-5\times 2^2=3-5\times 4 = 3-20=-17\\](https://tex.z-dn.net/?f=y%2B5x%5E2%3D3%5C%5C%5C%5C%3C%3D%3E%20y%3D3-5x%5E2%20%3Df%28x%29%5C%5C%5C%5C%5Ctext%7BSo%2C%20%7Df%28x%29%3D3-5x%5E2%5C%5C%5C%5Cf%282%29%3D3-5%5Ctimes%202%5E2%3D3-5%5Ctimes%204%20%3D%203-20%3D-17%5C%5C)

There's nothing I can do to help you understand this, you just have to memorize it.
2/3X-6 = -10
2/3x = -4
x = -4 / 2/3 = -6
X = -6
check:
2/3(-6) - 6 = -4 -6 = -10 TRUE
