Answer:
x=1
Step-by-step explanation:
given
21=14+7x
our objective is to get the variable (x) by itself
To do so we use inverse operations
so to get rid of the 14 we subtract 14 but whatever you do to one side you have to do to the other so we subtract each side by 14
14-14 cancels out
21-14=7
now we have
7x=7
now we want to get rid of the 7
to do so we divide by 7 but remember whatever we do to one side we have to do to the other side so we divide each side by 7
7/7 cancels out
7/7=1
we're left with x=1
hope this helps!

Not sure tho.....
Prime numbers are numbers that cannot be divided into further whole numbers. You cannot divide 19 and 13 because 13 and 19 are already prime numbers.
