Answer

Step 3: Solve the resulting equation for $y$ , then find the corresponding $x$ values: $y \approx - 1.9481, x \approx 12.2939$

Steps

Step 1 ：Step 1: Solve the second equation for $x$ : $x = \frac{- 5 y - 46}{3}$

Step 2 ：Step 2: Substitute this expression for $x$ into the first equation: $3 (\frac{- 5 y - 46}{3}) - 8 y^{4} = 19$

Step 3 ：Step 3: Solve the resulting equation for $y$ , then find the corresponding $x$ values: $y \approx - 1.9481, x \approx 12.2939$
