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 $$$\begin{cases} x^{2} - 4 y^{2} - 36=0 \\ x=- 3 \sqrt{5} \end{cases}$$$ for $$$x$$$, $$$y$$$.
Answer
$$$x=- 3 \sqrt{5}\approx -6.70820393249937$$$, $$$y=- \frac{3}{2}=-1.5$$$
$$$x=- 3 \sqrt{5}\approx -6.70820393249937$$$, $$$y=\frac{3}{2}=1.5$$$
