Before looking at how these are solved, be sure it is clear why they are linear. Then check that you see the algebraic steps in clearing the parentheses and isolating the variable.
- Solve for x:
- Solve for q:
To solve a linear equation, clear any parentheses and isolate the variable. Recall that a linear equation only involves the independent variable (x) to the first power (that, is, it has no terms like x2, 1/x, sin(x), etc.).
Be sure you've gone through each step in the examples above before doing these. Once you've worked them until you're sure that you understand them, go on to the next section. There are more problems of this type in the section test at the end of the section.
