Ok so 6x - 3y = -21
And 4x = 3y - 9
From the second equation, 4x - 3y = -9
So if you subtract the second from the first,
(6x-3y) - (4x-3y) = -21 - (-9)
So 2x = -12
x = -6
Now we know x=-6, and you can sub it back into any equation:
6(-6) -3y = -21
-36 - 3y = -21
-3y = 15
y = -5
So x=-6 and y=-5
Hope this helps
Answer:
2, 3, 5, 7, 11, 13.
Step-by-step explanation:
A prime number is a number that you don't get a whole number when divided by 2 but you do get a whole number when divided by prime numbers such as 3,5,7,11... Basically a number with two factors, it can only be divided by 1 or themselves. for example:
9/2 = 4.5 (this is not a whole number so it might be a prime.
9/3 = 3 (it works when divided by a prime number.
another:
8/2 = 4 (it gives a whole number when divided by 2 therefor, it can't be a prime number.
