$Solve for m: Understanding the Inequality $\frac{m}{2} < 2$$

Introduction

In mathematics, inequalities are a fundamental concept that help us compare values and solve problems. In this article, we will focus on solving the inequality $\frac{m}{2} < 2$ to find the value of $m$ . We will break down the solution step by step, using clear explanations and examples to ensure that you understand the concept.

Understanding the Inequality

The given inequality is $\frac{m}{2} < 2$ . To solve for $m$ , we need to isolate the variable $m$ on one side of the inequality. The inequality states that the value of $\frac{m}{2}$ is less than 2.

Step 1: Multiply Both Sides by 2

To isolate $m$ , we can multiply both sides of the inequality by 2. This will cancel out the fraction and give us the value of $m$ .

$\frac{m}{2} < 2$

Multiplying both sides by 2:

$m < 2 \times 2$

$m < 4$

Step 2: Write the Solution in Interval Notation

The solution to the inequality is $m < 4$ . We can write this in interval notation as $(-\infty, 4)$ .

Conclusion

In conclusion, to solve the inequality $\frac{m}{2} < 2$ , we multiplied both sides by 2 to isolate $m$ . The solution is $m < 4$ , which can be written in interval notation as $(-\infty, 4)$ .

Introduction

In our previous article, we discussed how to solve the inequality $\frac{m}{2} < 2$ to find the value of $m$ . In this article, we will answer some frequently asked questions about solving inequalities.

Q&A

Q: What is the difference between an inequality and an equation?

A: An inequality is a statement that compares two values using a symbol such as <, >, ≤, or ≥. An equation is a statement that states that two values are equal.

Q: How do I solve an inequality with a fraction?

A: To solve an inequality with a fraction, you can multiply both sides of the inequality by the denominator of the fraction. This will cancel out the fraction and give you the value of the variable.

Q: Can I add or subtract numbers to both sides of an inequality?

A: Yes, you can add or subtract numbers to both sides of an inequality, but you must do so in the same way to both sides. For example, if you have the inequality $x + 3 < 5$ , you can subtract 3 from both sides to get $x < 2$ .

Q: How do I solve an inequality with a variable on both sides?

A: To solve an inequality with a variable on both sides, you can add or subtract the same value to both sides of the inequality. For example, if you have the inequality $x + 2 = x + 3$ , you can subtract $x$ from both sides to get $2 = 3$ , which is a contradiction.

Q: Can I multiply or divide both sides of an inequality by a negative number?

A: No, you cannot multiply or divide both sides of an inequality by a negative number. This will change the direction of the inequality. For example, if you have the inequality $x < 2$ and you multiply both sides by -1, you will get $-x > -2$ , which is the opposite of the original inequality.

Q: How do I write the solution to an inequality in interval notation?

A: To write the solution to an inequality in interval notation, you can use the following notation:

$(-\infty, a)$ to represent all values less than $a$
$(a, \infty)$ to represent all values greater than $a$
$(-\infty, a]$ to represent all values less than or equal to $a$
$[a, \infty)$ to represent all values greater than or equal to $a$

Q: Can I use interval notation to represent a single value?

A: No, interval notation is used to represent a range of values, not a single value. If you want to represent a single value, you can use a number or a variable.
