Solution :-
2x - 9y = -1
2x = 9y - 1
x = 9y - 1 / 2 _________ (1)
Now, substitute it here!
-4x - 3y = - 19
-4 (9y - 1 /2) - 3y = -19
(-36y + 4 - 6y / 2) = -19
(-42y + 4 / 2) = -19
-42y + 4 = -38
-42y = -38 - 4
-42y = -42
y = 1
Value of x :
Substituting the value of y that is 1 in this equation. x = 9y - 1 / 2
x = 9(1) - 1 / 2
x = 9 - 1 / 2
x = 8 / 2
x = 4
