Introduction


In mathematics, inequalities are a fundamental concept that plays a crucial role in solving various problems. Inequalities are mathematical statements that compare two expressions, indicating that one is greater than, less than, or equal to the other. In this article, we will focus on solving linear inequalities, which are inequalities that can be written in the form of a linear equation. We will use the given inequality ${-3(4x - 3) + 3 \leq 3}$ as an example to demonstrate the step-by-step process of solving linear inequalities.

What are Linear Inequalities?


Linear inequalities are mathematical statements that compare two expressions, indicating that one is greater than, less than, or equal to the other. They can be written in the form of a linear equation, with the only difference being the use of the inequality symbol (>, <, or ≤) instead of the equality symbol (=). Linear inequalities can be classified into two types: strict inequalities and non-strict inequalities.

Strict Inequalities


Strict inequalities are inequalities that use the strict inequality symbols (>, <). They indicate that one expression is strictly greater than or strictly less than the other. For example, the inequality x>2x > 2 is a strict inequality.

Non-Strict Inequalities


Non-strict inequalities are inequalities that use the non-strict inequality symbols (≥, ≤). They indicate that one expression is greater than or equal to or less than or equal to the other. For example, the inequality x2x ≥ 2 is a non-strict inequality.

Solving Linear Inequalities


Solving linear inequalities involves isolating the variable on one side of the inequality symbol. The steps involved in solving linear inequalities are similar to those involved in solving linear equations, with the only difference being the use of the inequality symbol.

Step 1: Simplify the Inequality


The first step in solving a linear inequality is to simplify the inequality by combining like terms. This involves removing any parentheses and combining any like terms on the same side of the inequality symbol.

Step 2: Isolate the Variable


The next step is to isolate the variable on one side of the inequality symbol. This involves adding or subtracting the same value to both sides of the inequality to eliminate any constants on the same side as the variable.

Step 3: Solve for the Variable


Once the variable is isolated, the next step is to solve for the variable. This involves dividing both sides of the inequality by the coefficient of the variable to isolate the variable.

Solving the Given Inequality


Now that we have discussed the steps involved in solving linear inequalities, let's apply these steps to the given inequality ${-3(4x - 3) + 3 \leq 3}$.

Step 1: Simplify the Inequality


The first step is to simplify the inequality by combining like terms.

3(4x3)+33-3(4x - 3) + 3 \leq 3

12x+9+33-12x + 9 + 3 \leq 3

12x+123-12x + 12 \leq 3

Step 2: Isolate the Variable


The next step is to isolate the variable on one side of the inequality symbol.

12x+123-12x + 12 \leq 3

12x9-12x \leq -9

Step 3: Solve for the Variable


Once the variable is isolated, the next step is to solve for the variable.

12x9-12x \leq -9

x34x \geq \frac{3}{4}

Conclusion


In conclusion, solving linear inequalities involves isolating the variable on one side of the inequality symbol. The steps involved in solving linear inequalities are similar to those involved in solving linear equations, with the only difference being the use of the inequality symbol. By following the steps outlined in this article, you can solve linear inequalities with ease.
