Anton Christian · Answer 1

J + t = 30

j = 2t - 3

now we sub

(2t - 3) + t = 30

3t - 3 = 30

3t = 30 + 3

3t = 33

t = 33/3

t = 11 < = = Tritt's age

j = 2t - 3

j = 2 (11) - 3

j = 22 - 3

j = 19 < = = Jan's age

Bryanna Nguyen · Answer 2

2x-3+x=30

3x-3=30

3x=33

Tritts age=x=11

Jans age=2x-3=2 (11) - 3=22-3=19

Tritt=11

Jan=19
