7x-5y= -1
5x-7y= - 11
plz give me the answer with full explanation ​

Answer 1

Answer:

x+y = 5

x-y = -1

Step-by-step explanation:

7x-5y = -1 -------(i)

5x-7y = -11 -------(ii)

Subtracting eqn (ii) from eqn (i) we get:-

2x+2y = 10

=> x+y = 5

Adding eqn (i) and (ii) we get:-

12x-12y = -12

=> x-y = -1
