Answer 2

Answer:

x = 2 and y = 1

Step-by-step explanation:

→ 152x - 378y = - 74 ___(i)

→ - 378x + 152y = - 604 ___(ii)

Hence add and subtract both equations,

→ - 226x - 226y = - 678

→ - 226(x + y) = - 678

→ x + y = 3

&

→ 530x - 530y = 530

→ x - y = 1

Add both the equations,

→ 2x = 4

→ x = 2

Hence, y = 3 - x = 1
