не могу решить - помогите!!!

1) 8x2-23x+15>0
2) 2x-2>0
2)log_y(2x-2)<=log_y(1)

1) y=(x-1)(8x-15)>0
x-1>0----------x>1
8x-15>0------x>15/8>1.875
x>1.875

x-1<0----x<1
8x-15<0 ---x<1.875
x<1
(-oo;1)U(1.875,oo)

2) 2x-2>0
x>1

3) 2x-2<=1 --------2x<=3 ---x<=1.5

----------------------(-oo;1)U(1.875,oo) and (-oo;1.5] and (1;oo)
