Answer
$x = 2$
Answer for screen readers
The solution to the equation is $x = 2$.
Steps to Solve
- Subtract 1 from both sides
To isolate the term with $x$, subtract 1 from both sides of the equation:
$$ 2x + 1 - 1 = 5 - 1 $$
This simplifies to:
$$ 2x = 4 $$
- Divide by 2
Next, to solve for $x$, divide both sides by 2:
$$ \frac{2x}{2} = \frac{4}{2} $$
This gives:
$$ x = 2 $$
The solution to the equation is $x = 2$.
More Information
The solution $x = 2$ means that if you substitute 2 back into the original equation (2x + 1 = 5), the equation will hold true. This confirms that our solution is correct.
Tips
- Forgetting to subtract 1 from both sides, leading to the wrong equation.
- Miscalculating when dividing by 2, which may give an incorrect value of $x$.
