# Solving system of linear equations

Equation is non-linear.
Equation is not quadratic.
Equation is not cubic.

## The real roots of the equation:

x1 = -2.85786937156
x2 = -2.73325591833
x3 = 4.18651272066
x4 = 5.78629617322
x5 = 8.94695974511

Write each equation on a new line or separate by a semicolon. Online calculator solves a system of linear equations (with 1,2,...,n unknowns), quadratic equation with one unknown variable, cubic equation with one unknown variable and finally any other equation with one variable. This includes various goniometric, logarithmic and high degree equations. Even if an exact solution does not exist we calculate a numerical approximation of roots.

### Examples:

```a+b = 12
a-3b = a-b+43```
```x+y+z=100
3x-6y+2z=50
y-3z+x=(44-22)x+45```
`(x+4)(x-3)+34x+6x^2 = 256`
`(x+4)+34x+x^2-x^3 = -32`
`ln x = 1.2-x`
`sin x = cos(x-pi/3)+x`
`sin x = x^3+2x+x-1`
`sin x = 0.5`
`(cos x)^2 = tan(x-pi/3)`
`x^5+x^4 = -23+sin x`
`|log x|=2`
`|ln x+1|=x/10`
`|ln x+1|=ln x^2`
`1/(x+2)=1/x+4`
`sqrt(x^4+x^2+2)=22`
