Please do not keep posting the same problem over and over. You try to do this one, and I'll check your work in an hour.
12-9=15d+9
3=15d+9
3-9=15d
-6=15d
15d= -6
3*5*d= -3*2 Divide with 3
5d= -2 Divide with 5
d= -2/5= -0.4
3=15d+9
3-9=15d
-6=15d
15d= -6
3*5*d= -3*2 Divide with 3
5d= -2 Divide with 5
d= -2/5= -0.4
