-5n + 16

Step-by-step explanation:

Distribute the 7 to the equation inside the parenthesis.

7(n + 1) - 12n + 9

7n + 7 - 12n + 9

Bring the -12n towards the 7n.

7n - 12n + 7 + 9

Add or subtract like terms.

7n - 12n + 7 + 9

  -5n     +   16  

-5n + 16

distance covered by pamela in 9 l of fuel = 99km

let us apply unitary method here.

distance covered by pamela in 1 l of fuel =99/9 =11 km

now let us find distance covered by pamela if she has 12 l of fuel.

distance covered in 12 l = distance covered in 1 l of fuel * 12

we know that distance covered by here in 1 l is 11 km.

so distance covered in 12 l of fuel = 11*12 = 132 km.
