Concept explainers
Find when solving linear inequalities and linear equation similar.
Answer to Problem 72SR
The same processes are used when solving linear inequalities and equations that involve addition, subtraction, multiplication, division by a positive number.
Explanation of Solution
Given:
How are solving linear inequalities and linear equation similar?
Concept Used:
The same processes are used when solving linear inequalities and equations that involve addition, subtraction, multiplication, division by a positive number.
However, when a linear inequality is multiplied or divided by a negative number, the inequality symbol must change direction so that the inequality remains true.
Calculation:
For example:
Inequality:
Equation:
Thus, the same processes are used when solving linear inequalities and equations that involve addition, subtraction, multiplication, division by a positive number.
