Question

What is the solution to the linear equation?

d – 10 – 2d + 7 = 8 + d – 10 – 3d

d = –5
d = –1
d = 1
d = 5

Answer 1

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

-d - 3 = -2 - 2d

2d - d = -2 + 3

d = 1

Answer 2

d=1

Explanation:

Given :
`d -10 -2d + 7 = 8 + d- 10-3d`

To Find : What is the solution to the linear equation?

Solution :

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

`-d -3= -2d- 2`

`2d-d =3- 2`

`d =1`

Hence the value of d is 1

So, Option C is true.
