Log base 12 (2x-+6) + log base 12 (x+2) =2 how is this solved

Step-by-step explanation:

First step: Distribute the 12 to both parentheses, like so:

(12 x 2x) - (12 x 6) + (12 times x) + (12 x 2) = 2.

Second step: Multiply what's in the parentheses, like so:

(24x) - (72) + (12x) + (24) = 2.

Third Step: Combine like terms (terms that are alike), like so:

(24x + 12x) - (72 + 24) = 2.

Fourth Step: Add the like terms, like so:

36x - 96 = 2.

Fifth step: Add the negative 96 to both sides, like so:

36x - 96 = 2

       +96  +96

36x = 98.

Sixth step: Divide 36 on both sides, like so:

36x/36 = 98 / 36

1x = 2, or: x = 2

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.
