    Hi there. Try multiplying both sides by 5; what do you get?

    2*5 = a/5 * 5

    Basically, yes, your goal is to "isolate" the variable. Meaning, if it says "a - 5 = 4", you add 5 to both sides. Your goal is to get just the variable on one side, and everything else on the other.

    And to do the isolation, you must do the same thing to both sides of the equation at each step. As long as you do the same thing to both sides, the equation will keep being true.
