Explanation:

System of Linear Equations entered :

[1] 2x-y=4 [2] y-x=4

Equations Simplified or Rearranged :

[1] 2x - y = 4 [2] -x + y = 4

Graphic Representation of the Equations :

y + 2x = 4 y - x = 4

Solve by Substitution :

// Solve equation [2] for the variable y

[2] y = x + 4

// Plug this in for variable y in equation [1]

[1] 2x - (x +4) = 4 [1] x = 8

// Solve equation [1] for the variable x

[1] x = 8

// By now we know this much :

x = 8 y = x+4

// Use the x value to solve for y

y = (8)+4 = 12

Solution :

{x,y} = {8,12}

Hope you get it {2x−y=4 y−x=4-example-1
