Answer 2

Answer:

2

Step-by-step explanation:

n= 9q+7

3n-1 = 3(9q+7) - 1

= 27q + 21 - 1

= 27q + 20

when 3n - 1 is divided by 9 we have,

$\frac{27q + 20}{9}$

and then ,

$\frac{27q}{9} + \frac{20}{9}$

dividing by 9,

$3q + \frac{20}{9}$

when 20 is divided by 9 reminder is 2.

or,

$3q + \frac{18(2) + 2}{9}$

Therefore reminder when 3n-1 is divided by 9 = 2

The above can also be proved by doing division for linear polynomial. (see attachment) and please mark brainliest...
