#d=-1/4#

Explanation:

In a mathematical equation, you can perform any operation to any side, as long as you perform the same operation on the other side as well in order to keep the equation in balance.

So we perform operations such as to isolate the variable we are trying to solve for, in this case #d#.

So let us subtract #3/8# on both sides.

#therefore d+3/8-3/8=1/8-3/8#

#therefore d=-2/8#

#=-1/4# . (in simplest form).
