first thing, we move 3a

Answer 3

Answer 4

you would subtract so
d - 3a

Answer 5

d-3a=3b

Answer 6

good
now we need to isolate b so divide by 3

Answer 7

d/3-a = b

Answer 8

^?

Answer 9

no wait im lost

Answer 10

you were correct up til here
d - 3a = 3b
now we have to divide by 3 to get rid of the 3 attached to the b

Answer 11

okay but dividing d-3a lost me

Answer 12

cause d-a ain't a choice

Answer 13

no divide 3b/3 = b
divide 3 on the other side
\(\dfrac{d-3a}{3}=b\)
