9 is not a prime. 73 is a prime.
(1) 9x-2y=73 (2) 5x-9y=9 from (1) 9x-2y+2y=73+2y => 9x= 73+2y => x = (73+2y)/9 put into (2) 5x-9y = 9 => 5(73+2y)/9 - 9y=9 => 10y/9 + 365/9 -9y = 9 => 10y/9 - 9y = 9 -365/9 = -284/9 => -71y/9 = -284/9 => 71y= 284 => y = 284/71 = 4 and x = (73+2*4) / 9 = 9
4x + 9 = 73 4x = 64 x = 16
67 + 73 - 3 / 3 - 9 * 7 = 67 + 73 - 1 - 63 = 76.
73 is 9 more than the product of 4 and 16
73
9 is not a prime. 73 is a prime.
Nine does not go into 73 evenly, but 73 divided by 9 is 8 with a remainder of 1.
73+9+9-9-9=73, that's one way i see it. I answered the question of writing 73 by adding all those numbers and by using four nines.AnswerNoting that the value of 9 to the power zero equals 1, then using four nines we get: 73 = (9 x 9) - 9 + 9 0= 81 - 9 + 1 = 73

No.
It is: 64+9 = 73
67 + 73 - 3 / 3 - 9 * 7 = 67 + 73 - 1 - 63 = 76.
