-7
X - 7 = 11 X = 11+7 therefore X = 18 18 minus 7 equals 11.
6 times -7 is -42
42, because if there is nothing between the 7 and 'a' and 'a' equals 6 then the answer is 42.
12.
It is: 2n^2 -5n -42 equals (2n+7)(n-6) when factored

5/6 - 2/7 = 35/42 - 12/42 = 23/42 = 0.54762

7:25 minus 42 minutes is 6:43.
(-8) x (-7) - 14 = 42
It is a quadratic equation and the value of x is -7 or 6 x2 - 42 = (-x) x2 + x - 42 = 0 (x + 7) (x - 6) = 0
