Absolute Equations In this Problem, you need
to know about the symbol �|a|�, that means the �absolute�, or positive,
value of the number a. So, for example, |-5| = |5| = 5. A
How many pairs of integer values of x and y can you find to satisfy both
these equations simultaneously ?:
|x| + |y| = 3
and
|x - y| = 3 B And these two ?
|x + y| = 4
and
|x - y| = 8 C What difference now ?
|x + y| = 8
and
|x - y| = 4
