3m + 2n = 6---------------( 1 )
m + n = -24----------------( 2 )
from--------( 1 ) & --------( 2 )
multiply by ( 2 ) in -----( 2 )
3m + 2n = 6
2m + 2n = -48
-_____-____+
---------------------
m = 54 [ put in -----( 1 )]
3(54) + 2n = 6
162 + 2n = 6
2n = 6 - 162
2n = -156
n = - 78 , m = 54
m + n = -24----------------( 2 )
