Best ResponseYou've already chosen the best response.0With 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.

Best ResponseYou've already chosen the best response.0You 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.

Best ResponseYou've already chosen the best response.0Yes, to the left, center, and rightside expressions.

Best ResponseYou've already chosen the best response.0So, for the leftside, you get 3  1 because that is adding 3 to the left.

Best ResponseYou've already chosen the best response.0When 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.
