A. Write E if the following pairs of sets are equal and NE if not.
a. W = {a, b, a, c} Q = {a, b, c}
b. Z = {-3, 4} E = {4, 1}
c. K = { x|x is an integer and x<0}
U ={x|x is a negative integer}
d. H = {x|x is divisible by 7}
N = { …-14, -7, 0, 7, 14…}
e. J = { ….,-6, -3, 0, 3, 6,…}
L = { -6, -3, 0, 3, 6}
