Answer:u need help in general
Step-by-step explanation:
This is a Logic Problem. So we need to use operators to solve this problem. There are several operators in logic. Operators can be <em>monadic</em> or <em>dyadic</em>. A monadic operator operates on a single simple statement. Other operators will all be dyadic operators <span>because they operate on two simple statements. So in this problem we have the following operators:
</span>
1. The negation operator:
<u>Symbol:</u> ~
<u>Symbol name:</u> Tilde
<u>Parts of negation</u><span><u>:</u> A simple statement with a tilde preceding it</span>
2. Conjunction:
<u>Symbol:</u> &
<u>Symbol name:</u> Ampersand
<u>Parts of conjunction:</u> <span>Two simple statements joined by the conjunction symbol.
</span>
So we can name the statements as follows:
A: I am at home
B: I am playing video games
So the translations is as follows:
~(A&B) = It is not the case that I am at home and am playing video games

Answer:
x = 2, y = -1
Step-by-step explanation:
To find x, use elimination.
multiply everything in x - y = 3 by 2
(x - y = 3)2
that will now become 2x - 2y = 6
now line the equations up.
4x + 2y = 6
2x - 2y = 6
Now add everything going down.
4x + 2x is 6x, 2y and -2y cancel out, and 6 + 6 is 12. the equation is now:
6x = 12
divide on each side.
x = 2
to find y, substitute 2 into x - y = 3
2 - y = 3
-y = 1
y = -1
