Question

Can somebody help me? Preferably with working out if possible

Answer 1

Answer:

d=9

Step-by-step explanation:

First we can do same to both side by adding 2 to both sides:

1=1/3d-2

+2     +2

--------------

3 = 1/3d

Then to get the d on its own, we multiply each side by 3

3=1/3d

*3    *3

---------

9=d

Our final answer is 9

Answer 2

Answer:

d = 9

Step-by-step explanation:

Given

1 = $\frac{1}{3}$ d - 2 ( multiply through by 3 to clear the fraction )

3 = d - 6 ( add 6 to both sides )

9 = d
