SOLVE ATTACHMENT 30 POINTS!!!!!!

Masteriza [31]

Answer:

Step-by-step explanation:

$- 3 {f}^{3} + \frac{1}{6} MB = D$

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

$\frac{MB}{M} = \frac{6D + 18 {f}^{3} }{M}$

We have the final answer as

$B = \frac{6D + 18 {f}^{3} }{M}$

Hope this helps you
