See a solution process below:

First, subtract #color(red)(3.8v)# from each side of the equation to isolate the #v# term while keeping the equation balanced:

#-color(red)(3.8v) + 3.8v - 17.84 = -color(red)(3.8v) + 4.2v#

#0 - 17.84 = (-color(red)(3.8) + 4.2)v#

#-17.84 = 0.4v#

Now, divide each side of the equation by #color(red)(0.4)# to solve for #v# while keeping the equation balanced:

#-17.84/color(red)(0.4) = (0.4v)/color(red)(0.4)#

#-44.6 = (color(red)(cancel(color(black)(0.4)))v)/cancel(color(red)(0.4))#

#-44.6 = v#

#v = -44.6#
