Factor out the coefficient of the variable 1.7j-3.4

Here you would factor out a 1.7 because that is the coefficient in front of the j. When you factor, you are essentially dividing each term by the value you are factoring out
1.7j/1.7=j
-3.4/1.7=-2

So the final answer is 1/7(j-2)

Hope this helps
