Answer: Population density the United Kingdom 
A= 2.63
B= 2
Step-by-step explanation:
We know that, to calculate the population density, we will divide the population by the size of the area.
i.e. 
Given : Area of UK = 243,610 km²1
Population = 
Then, the population density the United Kingdom would be :
On comparing to 
, we get
A= 2.63
B= 2
We know that
The subtraction property of equality<span> tells us that if we subtract from one side of an equation, we also must subtract from the other side of the equation to keep the equation the same
that means
if a=b and c=d
a-c=b-d
</span>then
<span>−8x+4y=0----------> equation 1
a=(-8x+4y) b=0
−8x+7y=6----------> equation 2
c=(-8x+7y) d=6
therefore
</span>
(-8x+4y)-(-8x+7y)=0-6
-8x+4y+8x-7y=-6
-3y=-6
the answer is the option
Subtraction Property of Equality
Answer: -8
Step-by-step explanation:
3 - (-8) = 3+8
3+ 8=11
