y=2x-6;y=3x-8
Solution :
{y,x} = {-2,2}
System of Linear Equations entered :
[1] y - 2x = -6 [2] y - 3x = -8
Graphic Representation of the Equations :
-2x + y = -6 -3x + y = -8
Solve by Substitution :
// Solve equation [2] for the variable y
[2] y = 3x - 8
// Plug this in for variable y in equation [1]
[1] (3x-8) - 2x = -6 [1] x = 2
// Solve equation [1] for the variable x
[1] x = 2
// By now we know this much :
y = 3x-8 x = 2
// Use the x value to solve for y
y = 3(2)-8 = -2
Solution :
{y,x} = {-2,2}
