#u = -1.6#

Explanation:

To solve this, we need to make our variable #u# alone.

The first thing we do is subtract #color(blue)8.8# from both sides of the equation:
#5.6 quadcolor(blue)(-quad8.8) = 8.8 - 2u quadcolor(blue)(-quad8.8)#

#-3.2 = -2u#

Divide both sides by #color(blue)(-2)#:
#(-3.2)/color(blue)(-2) = (-2u)/color(blue)(-2)#

#-1.6 = u#

So the answer is #u = -1.6#

Hope this helps!
