Answer:

d = 31/8 or 3 and 7/8

Explanation:

1/2(2d - 3/4) + 2/5 = 4d/5

Distribute the 1/2 to the numbers in the parentheses

d - 3/8 + 2/5 = 4d/5

Combin the 3/8 and 2/5 by finding a common denominator

d - 31/40 = 4d/5

Multiply the 5 to cancel it out

5d - 31/8 = 4d

Move the 5d over

-31/8 = -d

Divide by -1 to make the -d positive

d = 31/8 or 3 7/8
