Lesson Summary:

In this first part of solving linear equations in one variable, we learn about the addition property of equality and how we can use it to solve equations. By adding or subtracting the same number to both sides of the equation, we can simplify the problem and find the solution. The lesson covers simple examples such as X+2=5 and more complex problems like 4+n=-9. The importance of checking the answer is also emphasized.
