Combine like terms. (-3x - 2) + (4y + 8x) + (3 + 7y)
(-3x – 2) +(4y +8x) + (3 + 7y) = (Simplify your answer.)

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.
