Because of the minus sign, 8 turns to -8, -8x3=-24.

(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
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
8x3=24
x + 12 < 73 x + 12 ≤ 73 x + 12 ≥ 73 and x + 12 > 73.
It completely depends on the value of 'x' .

2x + 6 = 2(x + 3) so 2x + 6 = 0 implies x = -3 Now, substitute x = -3 in 8x3 + 20x2 + 36 which is -8*27 + 20*9 + 36 = -216 + 180 + 36 = 0 So -3 is a root of 8x3 + 20x2 + 36 ie, by the remainder theorem, (x + 3) is a factor. Also, each of the coeffivcients in the expression is even, so 2 is also a factor. So 2*(x + 3) or (2x + 6) is a factor.
1 x 73, 73 x 1 = 73
If x=-17/73 then -x=17/73
