#3.7x=17.46+2.15#
#3.7x=19.61#
#x=19.61/3.7#

to divide multiply both by 100 to get the whole numbers

#19.61/3.7 *100/100 =1961/370#

....#1961:370=5#
#-1850#
when we subtract this, the result is: #111# .Since #111# cannot be divided by #370# , we add one more zero to #111# so it is #1110# and place comma or point (#,# or #.#) immediately after #5# so it is #5,# . Furthermore, we divide #1110# by #370#:
....#1110:370=3#
#-1110#

The result is: #5.3# or #5,3#
