-3 + 4 - 6 + 3 - 2 + 42 = 1 - 6 + 3 - 2 + 42 = - 5 + 3 - 2 + 42 = - 2 - 2 + 42 = - 4 + 42 = 38
12 - 3 + 42 = 51
42
2 - 5 - 42 + 3 = -42
(5+7-42)(24-2+3) = (12-42)(22+3) = (-30)(25) = -750
-21
3/7 + 1/6 = 18/42 + 7/42 = 25/42
903.
you add the together and get 46
1 + 2 + 3 + 4 + 6 + 7 + 12 + 14 + 21 + 28 + 42 = 140
4m + 9 + 5m - 12 = 42 9m -3 = 42 9m = 42 + 3 9m = 45 m = 5
If you mean: 3(2+4x) = 42 then the value of x works out as 3
