Step-by-step explanation:
2x - 3y = 12
5x + 3y = 9 -----(I)
2x - 3y = 12 ----- (II)
Add (I) and (II)
7x = 21
x = 3
Putting the value of x = 3 in (I) we get
5(3)+3y=9⇒15+3y=9⇒3y=9-15=-6⇒y=-2
Thus, (x, y) = (3, -6).

Step-by-step explanation:
3x+4y=2. -------1
3y +x=-1. --------2
1 implies 3x +4y =2
2 can be rewritten by multiply with(-3 )as.-3x -9y= 3 ------3
---------------
Add 1 and 3. -5y = 5
y = -1
put y in 2
3(-1) + x = -1
x = -1+3
x =2
