Solving Literal Equations

Exercise 1.3 - Solution

a
We want isolate on one side of the equation — it doesn't matter which one. This means that and must be moved to the other side. Thus, we'll add 5 and subtract on both sides.
b
In this equation all terms have a greatest common factor of meaning we can start by diving both sides by Then, we'll isolate using inverse operations.
c
All terms have a greastest common factor Thus, we'll divide both sides by  and then solve for
d
Here, and must be moved to isolate We'll start by adding to both sides, but it is also possible to begin with dividing by
It is now possible to write the fraction as a sum of two fractions.
