5d - 10 - 2d + 5 = 7 + 5d - 10 - 3d

d = 2

Step-by-step explanation:

5d - 10 - 2d + 5 = 7 + 5d - 10 - 3d

subtract 5d from both sides

5d - 5d - 10 - 2d + 5 = 7 + 5d - 5d - 10 - 3d

-10 - 2d + 5 = 7 - 10 - 3d

add 10 to both sides

-10 + 10 - 2d + 5 = 7 - 10 + 10 - 3d

-2d + 5 = 7 - 3d

add 3d to both sides

-2d + 3d + 5 = 7 - 3d + 3d

d + 5 = 7

subtract 5 from both sides

d + 5- 5 = 7 - 5

d = 7 - 5

d = 2
