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

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 .

answer: all of the odd numbers were opened

the first person was the one that was opening all of the lockers. since one is odd, this causes all of the odd number lockers to be opened in the end.
