For each of the following questions you will be asked to do one or more
of the following:
To solve a linear equation; or
To solve a linear inequality
When you provide a solution, you should provide the answer either as a
set of values enclosed in braces, e.g. x = {35}, or as an interval, e.g.
y = [-3,12), where a square brack indicates that the endpoint on the interval
is to be included and a parenthesis indicates that the endpoint is
not to be included. For intervals that extend to infinity, use
"inf" instead of ∞, e.g. z = [1,inf) or x = (-inf,-1]. If there
is no solution, give the result as an empty pair of braces {}. If the
answer requires multiple intervals or multiple discrete values, give
all the intervals and all the discrete values, but you must not give
overlapping intervals. You may need to draw some graphs for yourself
to avoid giving the answer as overlapping intervals.
In order to help you practice working with fractions, which you will
need to understand well to work with polynomials, all the numbers you
provide in your answers are to either be whole numbers, or rational
numbers reduced to lowest terms. No credit will be given for answers
as decimal fractions, nor for answers that contain fractions that
have not been reduced.
