$3$
Answer for screen readers
The final answer for the value of $x$ is $3$.
Steps to Solve
- Isolate the variable x
To isolate $x$, we need to eliminate the constant on the left side of the equation. We can do this by subtracting 7 from both sides.
$$ x + 7 - 7 = 10 - 7 $$
- Simplify the equation
Now, simplify both sides of the equation:
$$ x = 3 $$
The final answer for the value of $x$ is $3$.
More Information
When you isolate a variable, you are effectively solving for its value. In this case, starting with the equation $x + 7 = 10$, subtracting 7 gives us the answer directly. It's an essential skill in algebra.
Tips
- Forgetting to perform the same operation on both sides of the equation. Remember, whatever you do to one side, you must do to the other side.
- Miscalculating simple arithmetic. Double-check your addition and subtraction to avoid errors.
