To solve the inequality \( 2x < 4 \), you can follow these steps:
-
Divide both sides of the inequality by 2: \[ x < \frac{4}{2} \]
-
Simplify the right side: \[ x < 2 \]
Thus, the solution is \( x < 2 \).
Graphing the Solution
To graph this inequality on a number line:
- Draw a horizontal line (the number line).
- Put a point at \( x = 2 \).
- Since the inequality is "less than" (not "less than or equal to"), draw an open circle at \( x = 2 \) to indicate that \( 2 \) is not included in the solution.
- Shade the line to the left of the open circle to represent all the numbers less than \( 2 \).
If you need to represent it visually, simply draw an open circle at 2 and shade to the left.
The solution is:
\[ x < 2 \]
