The answer would be B (3, one-half)

Explanation:
If you add the two equations together, the +2y and -2y cancel out, leaving 3x=9.
So, we know that x is three (9/3=3)
Substitute x as 3 in either equation (I used the first)
3+2y=4
2y=1
y= 1/2

So, x is 3 and y is one-half, making the answer B

Was Lenin a hero who made life better for Russians or was he a villain who made it worse?
garik1379 [7]

Answer:

Let's consider Lenin, the man. The sheer authenticity of his passion cannot be doubted by anyone. He did not cynically exploit the Russian situation of 1917 to satisfy his lust for power. The revolution, which overthrew the Tsar and later installed the Communist regime, was not just a path to leadership for leadership's sake. Whatever anyone thinks of Lenin, we cannot deny his sincerity. He genuinely believed that Russia could achieve a Communist utopia, and that he would be the first step in the salvation of the nation.

Akimi4 [234]

Answer:

The war resulted in the death of more than half of Paraguayan population representing about 66% of the Paraguayan population.
