Point A would be the answer because...
The distance between A and C is point B, which doesn't land on -2
Point A lands on -2.
The distance between A and D would be points B and C, both don't land on -2.
The opposite of -2 would be positive 2 and thats point D.
I hope this helps love.

400 reduced by 3 times my age is 163
Blababa [14]
400 - 3x = 163

Add 3x to both sides.

400 = 163 + 3x

Subtract 163 to both sides.

237 = 3x

237/3 = 79

elena55 [62]
V is 4 more tha x
v=4+x
sum is no more than 14
v+x≤14

sub 4+x for v
4+x+x≤14
4+2x≤14
minus 4 both sides
2x≤10
divide both sides by 2
x≤5
5+4=9

the neighboor's age is at most, 5 years
and victoria is 9 at most
