Answer:

#x=18/13#
#y=(-28)/26#

Explanation:

#3x+2y=2# --------------------(1)
#2x-3y=6# --------------------(2)

#3x+2y=2# --------------------(1) #xx3#
#9x+6y=6# --------------------(3)

#2x-3y=6# --------------------(2) # xx2#
#4x-6y=12# -------------------(4)

#9x+6y=6# --------------------(3)
#4x-6y=12# -------------------(4) #3 +4#
#13x=18#
#x=18/13#

Substitute #x=18/13# in the equation (1)

#3xx18/13+2y=2#
#54/13+2y=2#
#2y = 2-54/13=(26-54)/13=(-28)/13#
#y=(-28)/13 xx1/2=(-28)/26#
#y=(-28)/26#
