Answer:
a=b/4
Step-by-step explanation:
subtract 4b from both sides to end up with a=b-3a and then add 3a to both sides to get 4a=b, and divide both sides by 4 to get a=b/4.
Answer:
a + 4b + 5b - 3a can only be solved by a little.
Step-by-step explanation:
a + 3a =3a.
4b + 5b = 9b.
we can't solve 9b - 3a, since they have different functions, so 9b - 3a is the answer.
