To solve this, you need to isolate/get the variable "n" by itself in the equation:

-\frac{6}{7} =\frac{n}{21}    Multiply 21 on both sides to get "n" by itself

(21)(-\frac{6}{7} )=(21)\frac{n}{21}

-\frac{126}{7} =n     Simplify the fraction

-18 = n

Alika [10]

Answer:

The answer is option D.

Step-by-step explanation:

(4a - b)(2a - 3b)

Expand the terms

We have

8a² - 12ab - 2ab + 3b²

Which is

8a² - 14ab + 3b²

That's option D.

Hope this helps you
