Answer 2

{x,y}={−1,1}

Explanation:

// Solve equation [2] for the variable x

[2] x = 3y - 4

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

[1] (3y-4) - 2y = -3

[1] y = 1

// Solve equation [1] for the variable y

[1] y = 1

// By now we know this much :

x = 3y-4

y = 1

// Use the y value to solve for x

x = 3(1)-4 = -1
