The answer is #b=1.9#.

Explanation:

To solve for a variable, you have to get the variable by itself, one one side. To do this in this problem, you have to understand what is happening to the variable, #b#. In this problem, #4.2# is being added to #b#.

So, you have to get the variable by itself. To do this, you have to do the inverse operation of what is currently happening to #4.2#. #4.2# is being added to #b#, so you have to subtract it from the left side. But remember! Whatever you do to one side, you have to do it to the other. Once we subtract the #4.2# from the left and the right sides, you will end up with your answer.

After you have solved this problem, you will end up with the answer #b=1.9#.
