Hi there!
Answer:
<u><em>A. 12. x=12 and 12=x</em></u>
Step-by-step explanation:
addition property of equality is adding the same number both sides of an equation does not change the equation.
subtraction property of equality is subtraction the same number from both sides of an equation does not change the equation.
multiplication property of equality is multiplying both sides of an equation by the same number does not change the equation.
division property of equality is dividing both sides of an equation by the same number non-zero number does not change the equation.
x-6=14-8
subtract by 6 both sides of an equation.
x-6=6
add by 6 both sides of an equation.
x-6+6=6+6
simplify.
6+6=12
x=12
12-6=6
Hope this helps!

Have a great day!
Answer: We have an odd number of pennies.
Step-by-step explanation:
So we have N pennies.
When we wan to divide the N pennies into groups of 2, we have a penny left over.
This means that N is not divisible by 2.
The problem is that there are infinite natural numbers that are not divisible by two, this is the set of odd numbers.
And remember that an odd number can be written as:
N = 2*k + 1.
where k is an integer.
Then we want to divide this by 2 (divide N into groups of 2)
we have:
N/2 = (2*k + 1)/2 = 2*k/2 + 1/2 = k + 1/2.
So we have k groups of 2 pennies, and a penny leftover that we can not divide into two.
