well possibles would be
96, 9+6=15, 15*6=90, 90*8
85, 8+5=13, 13*6=78, 78*8
74, 7+4=11, 11*6=66, 66*8
63, 6+3=9, 9*6=54, 54*8
52, 5+2=7, 7*6=42, 42*8
41, 4+1=5, 5*6=35, 35*8
30, 3+0=3, 3*6=18, 18*8=144 all above are also more than 2 digits so this problem is unsolvable unless the problem was not written correctly.
8times more than 6 times the sum of x and y means 8(6(x+y))=48(x+y)
id suggest rereading original question or discus this problem with the teacher/professor
