Bunti360: Shortcut : Subtract both the given equations, Now, Divide 25 on both sides, You will get x-y = 5, Now x = y+5 and keep this in any one of the equation ! Now you will get the answer ! - Just the shortest method I found !..

Here is the Solution :

Given Equations :

(1) 62x + 37y = 13,
(2) 37x + 62y = -112,

Subtract (2) from (1),
=> (1) - (2)

=> (62x-37x) + (37y-62y) = (13-(-112))
=> 25x - 25y = 125,

Dividing 25 on both sides,

=> x - y = 5,
=> x = 5 + y, ------ (3)

Substituting (3) in (1)

=> (62(y+5)) + 37y = 13,
=> 62y + 310 + 37y = 13,
=> 99y = -297,
=> y = -3, -----(4),

Substituting (4) in (3)

=> x = 5 + (-3)
=> x = 5 - 3
=> x = 2,

Therefore :

x = 2, and,
y = -3 !!..

So therefore we found the values of x and y i.e We solved the pair of linear Equations !.

If you have another easiest method please do notify me !.

Hope you understand, Have a Great day !.
Thanking you, Bunti 360 !..
