Question

solve : 152x-378y= -74, -378x+152y=-604

Answer 1

Hey !

152x - 378y= -74 ----> [ 1 ]

-378x+152y = -604 ----> [ 2 ]

Adding equation 1 and 2

====>
-226x + -226y = -678

x + y = 3 -----> [3]


Now ,
Subtracting equation 1 from 2 ,
-530x + 530y = -530

530y - 530 x = -530

x - y = 1 ----> [ 4 ]

Adding equation 3 and 4

2x = 4

x = 4/2

x = 2

Lets put this value of x in equation 3

2 + y = 3

y = 3 - 2

y = 1


Hope this Helps You !!
