3x+2y=41.................(1)
2x+3y=14...................(2)
now (1)*2-(2)*3 we get
6x+4y=82
-6x-9y=-42
-5y=40
y=-8
putting y=-8 in(1) we get
3x+2*(-8)=41
x=19
2x+3y=14...................(2)
now (1)*2-(2)*3 we get
6x+4y=82
-6x-9y=-42
-5y=40
y=-8
putting y=-8 in(1) we get
3x+2*(-8)=41
x=19

multiply eq.1 by 2,
2(3x+2y)=(41)2
multiply eq.2 by 3,
3(2x+3y)=(14)3
eq.1 6x+4y=82
eq.2(-)6x+9y=42
_______________
-5y=40
y=-8
and x=19.
2(3x+2y)=(41)2
multiply eq.2 by 3,
3(2x+3y)=(14)3
eq.1 6x+4y=82
eq.2(-)6x+9y=42
_______________
-5y=40
y=-8
and x=19.
man:
The main motto of using elimination method is to make the coefficient of x or y same in both the equation so the we can eliminate them and then find out the value of remaining variable.
