6d-24=11d-18d-54

6d-24=-7d-54

Move -7d to the other side

Sign changes from -7d to -7d

6d+7d-24=-7d+7d-54

13d-24=-54

Move -24 to the other side

Sign changes from -24 to +24

13d-24+24=-54+24

13d=-54+24

13d=-30

divide both sides by 13 to get d by itself

13d/13=-30/13

Answer:

d=-30/13

Answer:


d=-(30)/(13)

Explanation:

The given equation is


6d-24=11d-18d-54

We need to find the value of d.

Combined like terms on the right side.


6d-24=(11d-18d)-54


6d-24=-7d-54

Add 7d on both sides.


6d-24+7d=-7d-54+7d


13d-24=-54

Add 24 on both sides.


13d-24+24=-54+24


13d=-30

Divide both sides by 13.


d=-(30)/(13)

Therefore, the value of d is
d=-(30)/(13).
