Step-by-Step Solution

Answer

The solutions to the system of equations is 

$\left(-1,4\right),\left(-1,-4\right),\left(5,2\right),\left(5,-2\right)$

Step 1. Given Information.

Given to find the exact solutions of the system of equations:

$\begin{array}{l}{x}^2+2y^2=33\\ x^2+y^2-19=2x\end{array}$

Step 2. Explanation .

Solving the system of equations using graphic calculator:

From the graph, the two graphs intersect at the points 

$\left(-1,4\right),\left(-1,-4\right),\left(5,2\right),\left(5,-2\right)$

Step 3. Conclusion .

Hence, the solutions to the system of equations is 

$\left(-1,4\right),\left(-1,-4\right),\left(5,2\right),\left(5,-2\right)$
