Solve the following systems of equations:152x - 378y = - 74- 378x +158y = - 604

Answer»

152x - 378y = - 74

- 378x +158y = - 604

Adding (1) and (2)

⇒ -226x – 226y = -678

⇒ x + y = 3----- (3)

(1) – (2)

⇒ 530x – 530y = 530

⇒ x – y = 1 ------ (4)

Adding (3) and (4)

⇒ 2x = 4

⇒ x = 2

Thus,

y = 1
