Introduction to Solving Linear Inequalities

Solving linear inequalities is a fundamental concept in mathematics, and it plays a crucial role in various fields such as algebra, geometry, and calculus. In this article, we will focus on solving a linear inequality of the form $5y + 3 \ \textgreater \ -7y + 13$. Our goal is to isolate the variable $y$ and reduce any fractions to their lowest terms.

Understanding the Inequality

Before we start solving the inequality, let's understand the concept of inequalities. An inequality is a statement that compares two expressions using a mathematical symbol such as $\textgreater$, $\textless$, $\textgreater \textgreater$, or $\textless \textless$. In this case, we have the inequality $5y + 3 \ \textgreater \ -7y + 13$, which means that the expression $5y + 3$ is greater than the expression $-7y + 13$.

Isolating the Variable $y$

To solve the inequality, we need to isolate the variable $y$. We can do this by adding or subtracting the same value to both sides of the inequality. In this case, we can add $7y$ to both sides of the inequality to get:

5y+3+7y \textgreater −7y+13+7y5y + 3 + 7y \ \textgreater \ -7y + 13 + 7y

Simplifying the left-hand side of the inequality, we get:

12y+3 \textgreater 1312y + 3 \ \textgreater \ 13

Subtracting 3 from Both Sides

Next, we can subtract 3 from both sides of the inequality to get:

12y+3−3 \textgreater 13−312y + 3 - 3 \ \textgreater \ 13 - 3

Simplifying the left-hand side of the inequality, we get:

12y \textgreater 1012y \ \textgreater \ 10

Dividing Both Sides by 12

Finally, we can divide both sides of the inequality by 12 to get:

12y12 \textgreater 1012\frac{12y}{12} \ \textgreater \ \frac{10}{12}

Simplifying the left-hand side of the inequality, we get:

y \textgreater 56y \ \textgreater \ \frac{5}{6}

Conclusion

In conclusion, we have solved the linear inequality $5y + 3 \ \textgreater \ -7y + 13$ and isolated the variable $y$. We have reduced any fractions to their lowest terms and obtained the solution $y \ \textgreater \ \frac{5}{6}$. This solution means that the value of $y$ must be greater than $\frac{5}{6}$.

Final Answer

The final answer is $y \ \textgreater \ \frac{5}{6}$.
