, -​

Answer 1

Step-by-step explanation:

Add eq 1 and eq 2

you get

eq 3

and then substract eq2-eq1

we get eq 4

you solve eq. 3 and 4 get answer

Answer 2

Answer:

(x-y) = 3

Step-by-step explanation:

Firstly,

Add both the eqⁿs

by adding you get

36x - 36y = 108

take common on LHS

36 ( x-y) = 108

(x-y) = 108/ 36

x-y = 3 ans.
