(ii) 25x – 23y = -167; 23x – 25y = - 169.
Solution :​

Answer 1

Answer:

x=-3 and y=4 do you want explanation...?

Answer 2

Answer:

25x-23y=-167 eq 1

23x-25y=-169 eq 2

on adding 1 and 2

48x-48y=-336

48(x-y)= -336

(x-y)= -7___ eq 3

now sub. 2 from 1

2x+2y=2

2(x+y)=2

(x+y)=1___ eq 4

now add eq3 n eq4

2x=-6

x=-3

put x=-3 in eq4

-3+y=1

y=4
