this done by another methods, [ ELIMINATION METHOD ]
3x + 2y = 11 2x + 3y = 4
{3x+2y =11} * 3 {2x+3y = 4 } * 2 (by eliminating Y)
9x+6y=33 ----------[1] 4x+6y=8 ----------[2]
by subtracting [1] and [2]
9x + 6y = 33
- ( 4x + 6y = 8 )
___________
5x + 0 = 25
5x=25
x= 5
putting the value of x in [1]
3x5 + 2y = 11
15 + 2y = 11
2y= -4
y=-2
3x + 2y = 11 2x + 3y = 4
{3x+2y =11} * 3 {2x+3y = 4 } * 2 (by eliminating Y)
