Question

Please someone help please pls

Answer 1

a =
`(4d^3)/(7-m)`

Explanation:

Given

4d³ = 7a - ma ← factor out a from each term on the left side

4d³ = a(7 - m) ← divide both sides by (7 - m)

`(4d^3)/(7-m)` = a

Answer 2

hopefully this is correct idk if i’m right.
answer is a= 4d^3 + ma/7
