-4/15d-8

Explanation:

Assuming you meant 2/5(d-10)-2/3(d+6)

Let's apply the distributive property
[2/5(d)-2/5(10)]-[2/3(d)+2/3(6)]
\rArr[2/5d-4]-[2/3d+4]=2/5d-2/3d-8

Find the common multiple of the denominators ( least common denominator ), which is 5 • 3 = 15
(2/5xx3/3)d-(2/3xx5/5)d-8/15
\rArr6/15d-10/15d-8=-4/15d-8
