Solve {l}{f(x)=2x-4/5-x,xneq5}{g(x)=3x+7}

$$\left. \begin{array} { l } { f ( x ) = \frac { 2 x - 4 } { 5 - x } , x \neq 5 } \\ { g ( x ) = 3 x + 7 } \end{array} \right.$$

Evaluate (complex solution)

$$fx=\frac{2\left(x-2\right)}{5-x},\ x\neq 5,\ gx=3x+7$$

Solve for x

$$\left\{\begin{matrix}x=-\frac{-\sqrt{25f^{2}-4f+4}-5f+2}{2f}\text{, }&g=\frac{7\sqrt{25f^{2}-4f+4}}{8}-\frac{35f}{8}+\frac{19}{4}\text{ and }f\neq 0\\x=-\frac{\sqrt{25f^{2}-4f+4}-5f+2}{2f}\text{, }&g=-\frac{7\sqrt{25f^{2}-4f+4}}{8}-\frac{35f}{8}+\frac{19}{4}\text{ and }f\neq 0\\x=2\text{, }&f=0\text{ and }g=\frac{13}{2}\end{matrix}\right.$$

Solve for g

$$g=\frac{3x+7}{x}$$

$$f=-\frac{2\left(2-x\right)}{x\left(5-x\right)}\text{ and }x\neq 5\text{ and }x\neq 0$$
