#y=11,x=31#

#x-3y=-2, -2x+5y=-7#

#x-3y=-2##.................1#

#-2x+5y=-7.............2#

#2x-6y=-4#.....................3#=1 xx 2#

#-y=-11#............................#=2+3#

#y=11#

#5x-15y=-10#....................4#=1xx5#

#-6x+15y=-21.............5#= #2xx3#

#-x=-31#...............................=#4+5#

#x=31#

substitute # y=11,x=31 # in 1

#31-3(11)=-2#

#31-33=-2#

#-2=-2#
