Checking your answers for linear equations is super important, and it doesn’t have to be hard! I’ve found that following some easy steps can help. Here’s how I do it:

1. Solve the Equation: First, you need to find the value of the variable in your equation. For example, if you solve $2x + 3 = 11$ and find that $x = 4$, you can move on to the next step.

2. Substitute Back: Now, take the solution you found—$x = 4$—and plug it back into the original equation. So, you would replace $x$ in $2x + 3 = 11$.

3. Do the Math: Next, calculate the left side of the equation using your solution. With $x = 4$, it looks like this:

   $$2(4) + 3 = 8 + 3 = 11.$$

   This matches the right side of the equation.

4. Check Both Sides: Now, compare the result from your calculation (which is 11) to the original equation's right side (also 11). If they’re the same, then you’ve got the correct answer!

5. Double-Check if Needed: If the sides don’t match, go back and look through your steps. Check your math again or see if you made a mistake when solving the equation.

That’s all there is to it! With a bit of practice, these steps can help you catch errors before you move on to the next problem. Happy solving!
