152x - 378y = -74 ------------(1)

-378x + 152y = -604 ----------(2)

Adding (1) and (2)

152x - 378y - 378x + 152y = -74 - 604

-226x - 226y = - 678

226x + 226y = 678

226( x+y) = 678

(x+y) = 678/226

x+y = 3

x = 3-y

Putting the value of x in (1)

152 (3-y) - 378y = -74

456 - 152y - 378y = -74

456 + 74 = 152y + 378y

530y = 530

y = 530/530

y = 1

Putting the value of y in, x = 3-y

x = 3 - 1

x = 2

hence value of x = 2 and value of y = 1
