Answer 2

Answer:

x + y = 3 (eq. 1)

x - y = 5 (eq. 2)

let's solve for x using eq. 2

x = y + 5 (eq. 3)

let's substitute eq. 3 into eq. 1

(y + 5) + y = 3

2y + 5 = 3

subtract 5 from both sides

2y = -2

y = -1

let's substitute value of y into eq. 3 to get x

x = -1 + 5

x = 4

therefore, x = 4, y = -1
