Solving Linear Equations: A Basic Approach

The video tutorial explains how to solve the inequality 3l - 6 ≥ 8. It begins by introducing the problem and analyzing the given inequality. The instructor then demonstrates how to isolate the variable 'l' by adding 6 to both sides and dividing by 3, resulting in the solution l ≥ 14/3. The tutorial emphasizes the importance of maintaining the inequality sign when dividing by a positive number.

What is the initial inequality given in the problem?

• 3l - 6 ≥ 8

• 3l + 6 ≤ 8

• 3l - 6 ≤ 8

• 3l + 6 ≥ 8
