8 0
Solve equation [2] for the variable y


[2] y = x + 6

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

[1] (x +6) - 5x = 2
[1] - 4x = -4
// Solve equation [1] for the variable x


[1] 4x = 4

[1] x = 1
// By now we know this much :

y = x+6
x = 1
// Use the x value to solve for y

y = (1)+6 = 7
Solution
{y,x} ={7,1}
