nikki8 x-2y=-28;x-y=-2

Solution :

{x,y} = {24,26}

System of Linear Equations entered :

[1] x - 2y = -28 [2] x - y = -2

Graphic Representation of the Equations :

-2y + x = -28 y + x = -2
olve by Substitution :

// Solve equation [2] for the variable  x

[2] x = y - 2

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

[1] (y -2) - 2y = -28 [1] - y = -26

// Solve equation [1] for the variable  y

[1] y = 26

// By now we know this much :

x = y-2 y = 26

// Use the  y  value to solve for  x

x = (26)-2 = 24

Solution :

{x,y} = {24,26}
