12 + 4[5% - 4(x + 5)] = 7 - 5x

help

Step-by-step explanation:

12 + 4[5% - 4(x + 5)] = 7 - 5x

12 + 4•(5% - 4•(x + 5)) = 7 - 5•x

11x = -55

x = -5

step-by-step explanation:

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.
