#d=10.4#

Refer to the explanation for the process.

Simplify:

#18.44-2.2d=-2.1d+18.89-1.49#

Simplify the right side.

#18.44-2.2d=-2.1d+17.40#

Subtract #18.44# from both sides.

#-2.2d=-2.1d+17.40-18.44#

Simplify.

#-2.2d=-2.1d-1.04#

Add #2.1d to both sides.

#2.1d-2.2d=-1.04#

Simplify.

#-0.1d=-1.04#

Divide both sides by #-0.1#

#d=(-1.04)/-0.1#

#d=10.4# #larr# Two negatives make a positive.
