Answer 5

x,y} = {7,6}

System of Linear Equations entered :

[1] 2x + y = 20
[2] 6x - 5y = 12
Graphic Representation of the Equations :

y + 2x = 20 -5y + 6x = 12

Answer 6

/ Solve equation [1] for the variable y


[1] y = -2x + 20

// Plug this in for variable y in equation [2]

[2] 6x - 5•(-2x+20) = 12
[2] 16x = 112
// Solve equation [2] for the variable x


[2] 16x = 112

[2] x = 7
// By now we know this much :

x = 7
y = -2x+20
// Use the x value to solve for y

y = -2(7)+20 = 6
Solution :

{x,y} = {7,6}
