See a solution process below:

Explanation:

First, expand the term in parenthesis by multiplying each term within the parenthesis by the term outside the parenthesis:

#234 = color(red)(7)(6v + 2) + 2v#

#234 = (color(red)(7) xx 6v) + (color(red)(7) xx 2) + 2v#

#234 = 42v + 14 + 2v#

Next, group and combine like terms on the right side of the equation:

#234 = 42v + 2v + 14#

#234 = (42 + 2)v + 14#

#234 = 44v + 14#

Then, subtract #color(red)(14)# from each side of the equation to isolate the #v# term while keeping the equation balanced:

#234 - color(red)(14) = 44v + 14 - color(red)(14)#

#220 = 44v + 0#

#220 = 44v#

Now, divide each side of the equation by #color(red)(44)# to solve for #v# while keeping the equation balanced:

#220/color(red)(44) = (44v)/color(red)(44)#

#5 = (color(red)(cancel(color(black)(44)))v)/cancel(color(red)(44))#

#5 = v#

#v = 5#
