Hey there!
First, multiply the second equation by -2 as the problem states. When you multiply the second equation by -2, you get:
-2x+4y=2
Now, add this equation to the first equation in which you simply combine like terms:
2x+y=3
+
-2x+4y=2
=
5y= 5
In conclusion, the correct answer would be the first choice.

Answer:
7x7x7
Step-by-step explanation:
No. 0.2487 is not an interger.
There are two big reasons for this:
1). There is no such thing as an ' interger ',
so no number could be one.
You probably mean ' integer '.
2). An integer is a whole number ... a number
with no fraction part and no decimal part.
0.2847 is all decimal, and not even big enough
to make the smallest whole number. (That's ' 1 '.)
