To isolate a variable in a linear equation, you can follow these easy steps:

1. Find the variable: First, look for the variable you want to isolate. This could be something like $x$.

2. Use opposite operations: You want to do things that will move other parts of the equation away from the variable.

   For example, if you have $x + 3 = 10$, you need to subtract 3 from both sides.

3. Simplify: Keep simplifying the equation until the variable is by itself.

   So, from $x = 10 - 3$, we get $x = 7$.

And that’s it! Super simple!
