LINEAREQUATION (EquationArray)

• is the set of values.

## Description

• This function shows the solution for the Linear equation with two variables.
• In , is the set values for two equations.
• If a ,b and r are real numbers also a and b are not equal to 0,then ax+by=r is called a linear equation in two variables.
• Here x and y are two variables.
• The numbers a and b are called the coefficients of the equation.
• Also the number r is called the constant.
• There are three ways to solve the linear equation:
```1. Graphing method.
2. Substitution method.
3.elimination by addition method.
```
• This function will return the result as Error when the given parameters are non numeric.

## Examples

1. LINEAREQUATION([[1,1,5],[1,-1,3]]) = 4 1
2. LINEAREQUATION([[5,2,4],[-2,1,11]]) = -2 7
3. LINEAREQUATION([[7,-3,4],[10,6,-11]]) = -0.125 -1.625
