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 $$$\begin{cases} 4 x^{2} + 9 y^{2} - 36=0 \\ x=- \sqrt{5} \end{cases}$$$ for $$$x$$$, $$$y$$$.
Answer
$$$\left(x, y\right)=\left(- \sqrt{5}, - \frac{4}{3}\right)\approx \left( -2.23606797749979, -1.33333333333333\right)$$$
$$$\left(x, y\right)=\left(- \sqrt{5}, \frac{4}{3}\right)\approx \left( -2.23606797749979, 1.33333333333333\right)$$$
