-3(a-6)=-(4a-6)-3a
solve

a = 3/5

Step-by-step explanation:

-3(a - 6) = -(4a - 6) - 3a

=> -3a + 18 = -4a + 24 - 3a

=> 3a + 18 = -7a + 24

=> 10a = 6

=> a = 3/5

Hoped this helped.

a = -3

Step-by-step explanation:

-3(a-6)=-(4a-6)-3a

-3a+18 = -4a+6-3a

-3a+18 = -4a-3a+6

-3a+18 = -7a+6

-3a+7a = 6-18

4a = -12

4a/4 = -12/4

a = -3

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.

after simplifying it i got: -36.25 as my answer. hope that !
