Answer:
(x,y)=(-1,1)
Step-by-step explanation:
Given that,
3x + 5y = 2 .....(1)
6x - 10y = -16 ....(2)
Finding the value of x from equation (1).
Put the value of x in equation (2)
Put the value of y in equation (1) :
So, the solution of the equations is (-1,1).
B. 6, -3
2(6) + 2(-3) = 6
12 - 6 = 6

True, correct. The universal set
U
is characterized by ∀:∈
∀
x
:
x
∈
U
. Taking the complement yields a set
U
c
that is characterized by ∀:∉
∀
x
:
x
∉
U
c
. This is equivalent to the statement ¬∃:∈
¬
∃
x
:
x
∈
U
c
and hence
U
c
is an (the) empty set. (Depending on your theory, there may not be a unique empty set.)
