Answer:
d = 1 .
Step-by-step explanation:
Given : d – 10 – 2d + 7 = 8 + d – 10 – 3d.
To find : What is the solution to the linear equation.
Solution : We have given
d – 10 – 2d + 7 = 8 + d – 10 – 3d.
Combine like terms
d - 2d -10 + 7 = 8 -10 +d -3d .
-d - 3 = -2 -2d .
On adding both sides by 2d
-d + 2d -3 = -2 .
d - 3 = -2 .
On adding both sides by 3
d = -2 + 3.
d = 1 .
Therefore, d = 1 .
