18+(9*3) = 45
x equals 9
-6x+9 = 45 -6x = 45-9 -6x = 36 x = -6
x = -6

-45 over 9 = -5 -5 plus 5 = 0 QED -45 over (9 plus 5) is a different matter and = -3.2143.
9x = 4x + 45 5x = 45x = 9
The LCF is 45 because 15 x 3 equals 45 and 9 x 5 equals 45. Now, multiply 8 x 3 to get 24 and 2 x 5 equals 10. 24 plus 10 equals 34. The answer is 34 over 45.
Since 2 plus 4 is not 10, the "if" statement is false. Given a false "if", logically, 9 + 2 can equal anything you like.
