Answer: A composite number can be divided into a whole number other than itself and one. A prime number can only be divided by itself and one.

Step-by-step explanation: Ex: 1,2,3,5,7,11,13, etc are prime. 4,6,8,9, etc are composite numbers. So... the first list is correct because 6 (3*2), 24(6*4), 51 (3*17), 105 (5*21) can all be multiplied by integers other than itself and one.

Rashid [163]

5x + 2y = 7....multiply by -3
-2x + 6y = 9
----------------
-15x - 6y = -21 (result of multiplying by -3)
-2x + 6y = 9
---------------add
-17x = - 12
x = 12/17 or 0.7

5x + 2y = 7
5(12/17) + 2y = 7
60/17 + 2y = 7
2y = 7 - 60/17
2y = 119/17 - 60/17
2y = 59/17
y = 59/17 * 1/2
y = 59/34 or 1.7 when rounded <====
