Answer:
[tex]d=14.5[/tex]
Step-by-step explanation:
Given equation:
[tex]d - 10 - 2d + 7 = 8 + d - 10 - 30[/tex]
To solve the equation for 'd', take the terms of 'd' to one side and the constants to the other side.
[tex]d - 2d - d = 8 - 10 - 30- 7+10[/tex]
[tex]-2d=8-30-7\\-2d=1-30\\-2d=-29\\ d=\frac{29}{2}\\ d=14.5[/tex]
On, solving the equation the value of 'd' is [tex]d=14.5[/tex]
