Answer 1

Here’s my answer, hope it’s right:

Answer 2

`B = \frac{6D + 18 {f}^(3) }{M}`

Explanation:

`- 3 {f}^(3) + (1)/(6) MB = D`

Multiply through by 6 to eliminate the fraction

That's

`- 18 {f}^(3) + MB = 6D`

Move - 18f³ to the right side of the equation

That's

`MB = 6D + 18 {f}^(3)`

Divide both sides by M to make B stand alone

That's

`(MB)/(M) = \frac{6D + 18 {f}^(3) }{M}`

We have the final answer as

`B = \frac{6D + 18 {f}^(3) }{M}`

Hope this helps you
