# Solving system of linear equations

### Solution:

x+y=70
48*x+52*y=3484

x+y = 70
48x+52y = 3484

x = 39
y = 31

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`
