Question

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

Answer 1

You have to simplify.
-d-3=-2-2d
-1=-d
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 : 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 .
