3/15 -(d/5)=5/6+(d/3)
-(d/5)-(d/3)=5/6-3/15

-(8d/15)=19/30
-8d=19/2
-d=76
d=-76

(3)/(15)-
(d)/(5)-(
(5)/(6)+
(d)/(3)=0

Step 1:
(5)/(6)+
(d)/(3)=
(3)/(15)- (d)/(5)- ((2d+5))/(6)=0

Step 2:
(1)/(5)- (d)/(5)= ((1-d))/(5)- ((2d+5))/(6)=0

Step 3:
((1-d)*6-(2d+5)*5)/(30)= (-1*(16d+19))/(30)

Step 4:
16d= -19:Divide \ both \ sides \ by \ 16:d= (-19)/(16)= -1.188

Your answer is
d\boxed{\boxed={ (-19)/(16)= -1.1888}}}}
