System of Linear Equations entered :

<1> y=1/2x-6 <2> x-4

Equations Simplified or Rearranged :

<1> y - x/2 = -6 <2> x = 4// lớn remove fractions, multiply equations by their respective LCDMultiply equation <1> by 2// Equations now take the shape:

<1> 2y - x = -12 <2> x = 4

Graphic Representation of the Equations :

x + 2y = -12 x = 4

Solve by Substitution :

// Solve equation <2> for the variable x

<2> x = 4

// Plug this in for variable x in equation <1>

<1> 2y - (4) = -12 <1> 2y = -8// Solve equation <1> for the variable y

<1> 2y = - 8 <1> y = - 4

// By now we know this much :

y = -4 x = 4We are done

Solution :

y,x = -4,4
