63 plus 47 plus 42 plus 21 is equal to 173.
63
If: 6b+21 = 7b-21 Then: 6b-7b = -21-21 And: -b = -42 So: b = 42
1 + 2 + 3 + 4 + 6 + 7 + 12 + 14 + 21 + 28 + 42 = 140
All that can be deduced is that x + y = 14.
13/14 + 5/6 = 39/42 + 35/42 = 74/42 = 37/21 or 116/21
It is a symbolic equation which requires triangle = 21.
2x - 13x + 42 = x +ax + b a + b = 2(x - 6.5x + 21) = 34 = a + b
k = 14/43
1 x 42, 2 x 21, 3 x 14, 6 x 7, 7 x 6, 14 x 3, 21 x 2, 42 x 1 = 42
-2x = 12 so x = -6 giving -30 + 9 = -42 + 21. Both sides = -21.
1 x 42, 2 x 21, 3 x 14, 6 x 7, 7 x 6, 14 x 3, 21 x 2, 42 x 1 = 42
