System of Linear Equations entered :

[1] 4x + 6y = -8

[2] 5x + 3y = 25

Graphic Representation of the Equations :

6y + 4x = -8 3y + 5x = 25

Solve by Substitution :

// Solve equation [2] for the variable y

[2] 3y = -5x + 25

[2] y = -5x/3 + 25/3

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

[1] 4x + 6•(-5x/3+25/3) = -8

[1] -6x = -58

// Solve equation [1] for the variable x

[1] 6x = 58

[1] x = 29/3

// By now we know this much :

x = 29/3

y = -5x/3+25/3

// Use the x value to solve for y

y = -(5/3)(29/3)+25/3 = -70/9

Solution :

{x,y} = {29/3,-70/9}
