The fractions are not lining up properly. I hope you can follow this.
First notice that you only have one denominator. So the LCD is 2a-5. If we multiply both sides by 2a-5 we get:
9
_____=-2
2a-5
(2a-5)9
_______=-2(2a-5)The (2a-5)'s cancel on the left.
(2a-5)
9=-2(2a-5)
9=-4a+10
9-10=-4a+10-10
-1=-4a
-1/-4=-4a/-4
1/4=a
