#x = 4.65# rounded to the nearest hundredth.

First, subtract 3.14 from each side of the equation to isolate the #x# term and keep the equation balanced:

#1.04x + 3.14 - 3.14 = 7.98 - 3.14#

#1.04x + 0 = 4.84#

#1.04x = 4.84#

Then, divide each side by #1.04# to solve for #x# while keeping the equation balanced:

#(1.04x)/1.04 = 4.84/1.04#

#(cancel(1.04)x)/cancel(1.04) = 4.65#

#x = 4.65# rounded to the nearest hundredth.
