Solve the equation h - 3 = 18.
Understand the Problem
The question is asking to solve the equation h - 3 = 18 for the variable h. This involves isolating h on one side of the equation to find its value.
Answer
$h = 21$
Answer for screen readers
The value of $h$ is $21$.
Steps to Solve
- Add 3 to both sides of the equation
To isolate $h$, we need to eliminate the $-3$. We do this by adding 3 to both sides of the equation:
$$ h - 3 + 3 = 18 + 3 $$
This simplifies to:
$$ h = 21 $$
- Final Equation
Now we have isolated $h$. The final equation shows the value of $h$:
$$ h = 21 $$
The value of $h$ is $21$.
More Information
The equation $h - 3 = 18$ represents a simple linear equation. By performing basic arithmetic to isolate the variable, we find that $h$ has a value of 21. This process is fundamental in algebra and helps build skills for solving more complex equations.
Tips
- Forgetting to perform the same operation on both sides of the equation can lead to incorrect answers. Always remember to keep the equation balanced.
- Overcomplicating the process by making unnecessary steps. Keep it simple!
