Chapter 2: Linear Equations
2.3 Intermediate Linear Equations
When working with linear equations with parentheses, the first objective is to isolate the parentheses. Once isolated, the parentheses can be removed and then the variable solved.
Example 2.3.1
Solve for in the equation
Example 2.3.2
Solve for in the equation
For some problems, it is too difficult to isolate the parentheses. In these problems, it is necessary to multiply or divide throughout the parentheses by whatever coefficient is in front of it.
