Answer:
Answer shown from explanation
Step-by-step explanation:
|x| means modulus of x such that positive or negative value of x evaluates to a positive value.
|x| = 7 is the same as x = -7 and x = 7
Similarly,
|y| = 13 is the same as y = -13 and y= 13;
Hence the possible values are;
7+13= 20
7-13= -6
-7-13= -20
-7 + 13 = 6
Answer:
20, -20, -6, 6
Step-by-step explanation:
