a) \( -3+x=-3 \)

To solve the equation \( -3+x=-3 \), start by isolating \( x \). You can do this by adding 3 to both sides of the equation. This simplifies to \( x = -3 + 3 \), which gives you \( x = 0 \). So, the solution is \( x = 0 \). It's like finding out that if you owe three apples and then you don’t owe any, you must have none left! Now, let’s think about the interpretation! This equation tells us something quite interesting about balancing numbers. Imagine if a magician says, "I’ve taken three away," but in truth, you've returned three! You’ve effectively balanced the scales back to zero. It’s a playful reminder that in equations, what you do to one side, you must always do to the other to maintain balance!
