R+14=39
r + 14 = 39 r = 25
12r = p

25
It is |r - s| + 14 or abs(r - s) + 14.
R+14=39
R+14=39
r + 14 = 39 r = 25
12r = p
25
39-14=25 so R=25 25+14=39
25
r = 25
Sesame Street - 1969 Letter 'R' Mystery 42-14 was released on: USA: 11 November 2011
The factors of 42 are: 1, 2, 3, 6, 7, 14, 21, 42 The factors of 49 are: 1, 7, 49
Lets call them R for Rex, F for Father and M for Morther F - 30 = R M = 3R F - 2 = M If we subtract the third equation from the first one we get F - 30 = R F - 2 = M ------------ 0 - 28 = R - M or M - R = 28 Now, if M = 3R we can substitute that into the above and we ger 3R - R = 28 2R = 28 R = 14 So, if Rex is 14, his mother is 3 x 14 = 42 and his father is 14 + 30 = 44 - which is 42 + 2.
