Question

D - 10 - 2d + 7 = 8 + d - 10 - 30

Answer 1

D= 14.5 I promise dawg

Answer 2

`d=14.5`

Explanation:

Given equation:

`d - 10 - 2d + 7 = 8 + d - 10 - 30`

To solve the equation for 'd', take the terms of 'd' to one side and the constants to the other side.

`d - 2d - d = 8 - 10 - 30- 7+10`

`-2d=8-30-7\\-2d=1-30\\-2d=-29\\ d=(29)/(2)\\ d=14.5`

On, solving the equation the value of 'd' is
`d=14.5`
