To solve this, we have to isolate the variable on one side of the equation.
<u>Given:</u>
<u />
<u>Subtract both sides by </u>

Your answer is:

The operation indicated, A - B, is a subtraction of sets.
The subtraction of set B from set A means that you have to remove the elements of B that are on A; i.e. A - B = {15, 35, 55}
25, 45 and 65 (which are in the set B) were removed from the set A to form the set A - B
