solve a system of equations
... We have previously discussed equations in two variables, such as x + y = 3. Because there are infinitely many pairs of numbers whose sum is 3, there are infinitely many pairs (x, y) that satisfy this equation. Some of these pairs are listed in table (a). Now consider the equation x − y = 1. Because ...

... variables, it is easy to think that you have a solution that yields a false statement! If you do the problem by moving the constants first you will get a variable expression that equals a different variable expression. This can be mistaken as a false statement but you can not yet determine this beca ...
