Answer 1

`0.2(d-6)=0.3d+5-3+0.1d`

To solve for d:

1. Remove parenthesis:

`0.2d-1.2=0.3d+5-3+0.1d`

2. Leave the terms with d in one side of the equation:

-Add 1.2 in both sides of the equation:

`\begin{gathered} 0.2d-1.2+1.2=0.3d+5-3+0.1d+1.2 \\ 0.2d=\text{0}.3d+5-3+0.1d+1.2 \end{gathered}`

-Substract 0.3d and 0.1d in both sides of the equation:

`\begin{gathered} 0.2d-0.3d-0.1d=0.3d-0.3d+5-3+0.1d-0.1d+1.2 \\ 0.2d-\text{0}.3d-0.1d=5-3+1.2 \end{gathered}`

3. Opperate similar terms:

`-0.2d=3.2`

4. Divide into (-0.2) both sides of the equation:

`\begin{gathered} (-0.2)/(-0.2)d=(3.2)/(-0.2) \\ \\ d=-16 \end{gathered}`Then, d is -16
