With inequalities, you can add or subtract numbers to all sides and retain the direction of the sign. So, find a number such that if you add it to "a  3" you end up with "a". Take that number and add it to all 3 expressions.

You are looking for (a  3) + x = a That is the same as: a + (x  3) = a So, you are looking for where x  3 = 0. What is "x"? You add whatever "x" is to all 3 expression and you get "a" all by itself.

Yes, to the left, center, and rightside expressions.

So, for the leftside, you get 3  1 because that is adding 3 to the left.

When you add 3 to the center expression, you get (a  3) + 3 = a + (3  3) = a + 0 = a, which is what you want. The rightside expression, before simplifying, is 2 + 3.
