Question

What is solution to the linear equation d- 10-2d+7=8+d-10-3d

Answer 1

d-10-2d+7=8+d-10-3d
-d-3=-2d-2
d-3=-2
d=1

Answer 2

Answer: The required solution of the given equation is d = 1.

Step-by-step explanation: We are given to find the solution to the following linear equation :

`d-10-2d+7=8+d-10-3d~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(i)`

To solve the above equation, we need to find the value of the unknown variable d.

The solution of equation (i) is as follows :

`d-10-2d+7=8+d-10-3d\\\\\Rightarrow -d-3=-2d-2\\\\\Rightarrow -d+2d=-2+3\\\\\Rightarrow d=1.`

Thus, the required solution of the given equation is d = 1.
