Heya.....!!!!
______________________________
Given 2 equations :-
=> 2x + 3y = 20
=> 2x - 3y = -4
Add these both equations :
=> 4x = 16
=> x = 16 / 4
→ x = 4
So y will be = 4
The Value of => 2 ( x - y ) will be :-»
=> 2 ( 4 - 4 )
➡ 0 is the answer .
==================================
Hope It Helps You ☺

2x + 3y = 20 ...... -1
2x - 3y = -4 ........ -2
Adding 1 and 2,
We get,
4x = 16
x = 4.
Substituting x in equation 1
2(4) + 3y = 20
8 + 3y = 20
3y = 12
y = 4
And so,
2(x-y)= 2(4-4) = 0
2x - 3y = -4 ........ -2
Adding 1 and 2,
We get,
4x = 16
x = 4.
Substituting x in equation 1
2(4) + 3y = 20
8 + 3y = 20
3y = 12
y = 4
And so,
2(x-y)= 2(4-4) = 0
