solve the following system of equation :

15x +23y = 50

23x + 15y= 26

Condition 1 :-
Add both eqn :-
38x + 38y = 76 
= x + y = 2 ----------- 1 )

Condition 2 :-
Subtract both eqns :-
- 8x + 8y = 24
= x - y = - 3 --------- 2 )

Eliminating eqn 1 and 2 we get :-
2y = 5
y = 5 / 2 ------- 3 )

Substituting 3 ) in eqn 2 ) we get :-

x - 5 / 2 = - 3
x = - 1 / 2  ----------- 4 )

Hope it helps ..!!!
