Answer 1

7 x 4 - 3 x 1 = 28 - 3 = 25
7 x 5 - 3 x 1 = 35 - 3 = 33
7 x 6 - 3 x 1 = 42 - 3 = 39
7 x 5 - 3 x 2 = 35 - 6 = 29
7 x 6 - 3 x 2 = 42 - 6 = 36
7 x 7 - 3 x 2 = 49 - 6 = 43
7 x 5 - 3 x 3 = 35 - 9 = 26
7 x 6 - 3 x 3 = 42 - 9 = 33
7 x 7 - 3 x 3 = 49 - 9 = 40
7 x 6 - 3 x 4 = 42 - 12 = 30
7 x 7 - 3 x 4 = 49 - 12 = 37
7 x 8 - 3 x 4 = 56 - 12 = 44
7 x 6 - 3 x 5 = 42 - 15 = 27
7 x 7 - 3 x 5 = 49 - 15 = 34
7 x 8 - 3 x 5 = 56 - 15 = 41
7 x 7 - 3 x 6 = 49 - 18 = 31
7 x 8 - 3 x 6 = 56 - 18 = 38
7 x 9 - 3 x 6 = 63 - 18 = 45
