Question 17106: I am trying to solve an inverse operation problem using fractions.
the problem is
8/11-x=2/11
I must show work, but am having a problem solving the correct way. I know the answere is 6/11, but how am I finding that.
I have tried
8/11-x+x=2/11+x
8/11=2/11+x
8/11-2/11=2/11-2/11+x
6/11+x
