Add #4.3# to each side and divide each side by #1.2#. To check you solution, substitute your answer for #j#.

First, let's add 4.3 to each side:

#1.2j-4.3+4.3=1.7+4.3#

#1.2j=6#

Next, divide each side by #1.2#:

#(1.2j)/1.2=6/1.2#

#j=5#

To check your answer, substitute #5# for #j#:

#1.2(5)-4.3=1.7#

#6-4.3=1.7#

#1.7=1.7#

Our answer is #5#.
