105.
a=24 b=16 c=18
The LCM is 9324.
b = 40 - a, c = 42 - a so b + c = 40 - a + 42 - a, ie 82 -2a = 34 so a = 48/2 ie 24 b = 40 - 24 ie 16 and c = 42 - 24 ie 18
42 + 42 = 84
5+x=42. 42-5=37 x=37

-6
The LCM is 9324.
4x - 5 + 2x = 376x - 5 = 376x = 37 + 56x = 42x = 42 / 6x = 7
b = 40 - a, c = 42 - a so b + c = 40 - a + 42 - a, ie 82 -2a = 34 so a = 48/2 ie 24 b = 40 - 24 ie 16 and c = 42 - 24 ie 18
42 + 42 = 84
18 + 42 = 60
42 + 24 + 18 = 84
