Question

#4. Determine d in the equation.

14.2 = −1.4 − 3d

d = −5.2
d = −4.3
d = 4.3
d = 5.2

Answer 1

d = - 5.2

Explanation:

14.2 = - 1.4 - 3d

14.2 + 1.4 = - 3d

15.6 = - 3d

15.6/3 = - d

5.2 = - d

- d = 5.2

d = -5.2

Hope this helps.

Answer 2

Answer: d = -5.2

Starting equation:
`14.2=-1.4-3d`

`\mathrm{Switch\:sides}`:
`-1.4-3d=14.2`

`\mathrm{Add\:}1.4\mathrm{\:to\:both\:sides}`:
`-1.4-3d+1.4=14.2+1.4`

`Simplify`:
`-3d=15.6`

`\mathrm{Divide\:both\:sides\:by\:}-3:`
`(-3d)/(-3)=(15.6)/(-3)`

And your finial answer is: -5.2
