3x - 2y = 4   (i) \\ x + y = 3(ii)
NOW, IN EQ. ii. I'LL MULTIPLY 3.i.e.*3
so, new EQ. will be
3x + 3y = 9
SO, 3X AND 3X WILL CANCEL OUT AND...
 - 2y - 3y =  - 5y
and...
4 - 9 =  - 5
so, -5y=-5 . MINUS WILL BE CANCEL.
SO, Y= 5/5 =1
y = 5 \div 5 = 1
put 1 in the EQ. and get the value of x
so,
x + y = 3
x+1=3
x=3-1
x=2
MARK IT AS A BRAINLIST... PLS
