# System of Equations Calculator

## Solve system of equations

This solver (calculator) will try to solve a system of 2, 3, 4, 5 equations of any kind, including polynomial, rational, irrational, exponential, logarithmic, trigonometric, hyperbolic, absolute value, etc. It can find both the real and the complex solutions. To solve a system of linear equations with steps, use the system of linear equations calculator.

**Your input: solve $$$\begin{cases} 2 x^{2} + 9 y^{2} - 18=0 \\ x=\sqrt{7} \end{cases}$$$ for $$$x$$$, $$$y$$$.**

### Answer

$$$x=\sqrt{7}\approx 2.64575131106459$$$, $$$y=- \frac{2}{3}\approx -0.666666666666667$$$

$$$x=\sqrt{7}\approx 2.64575131106459$$$, $$$y=\frac{2}{3}\approx 0.666666666666667$$$
