Fraction r over s equals 5 over 8 r plus s equals 39 what are r and s?
15 and 24, respectively.
R plus s equals 4 2r plus 3s equals 8?
r + s = 4 and 2r + 3s = 8 multiply the first equation by 2 giving 2r + 2s = 8 subtract this from the second equation giving s = 0 So r = 4 and s = 0.
What is the order of the linked genes r s and t if the distance between r and s is 22 mu the distance between s and t is 8 mu and the distance between r and t is 14 mu?
r-t-s

Frank is 3 times as old as Sue and 15 years older than John while Sue is 1 year younger than John How old is Frank?
Frank is 24. Sue is 8 and John is 9. F = 3S F = J + 15 S = J - 1 Where F is Frank's age, S is Sue's age, and J is John's age. You can substitute J - 1 for S in the first equation: F = 3(J - 1) Then replace F with the expression from the second equation: J + 15 = 3(J - 1) 2J = 18 J = 9 S = 8 F = 24 --- You could also put both expressions in terms of the smallest value, S F = 3S F = 15 + (S +1) 3S = 16 + S 2S = 16 S = 8 F = 24
