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. Note that you can get
