Answer:

{y,x} = {0,4}

Explanation:

// Solve equation [2] for the variable y

[2] y = 2x - 8

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

[1] (2x-8) + x = 4

[1] 3x = 12

// Solve equation [1] for the variable x

[1] 3x = 12

[1] x = 4

// By now we know this much :

y = 2x-8

x = 4

// Use the x value to solve for y

y = 2(4)-8 = 0
