X + x + 2 + x + 4 = -213
3x + 6 = -213
3x = -219
x = -73
-73 + 2 = -71
-73 + 4 = -69
Solution: -73, -71, -69

V=1,436.03
For #1, I have attached the number line.
For #2, I have provided two examples. One shows a different any quality symbol, and the other one shows the same based on absolute values.
For #3, you can see using the number line that -0.5 is the closest to zero.
