Seth is 4 years older than Anna.Two years ago Seth was 3 times older than Anna was then How old are seth and Anna now

Answer 1

S=4+A

S-2 =3(A-2) = 3A-6

S= 3A-4

4+A = 3A-4

2A = 8

A = 8/2 = 4 years old for Anna now

S= 3A-4= 3(4)-4= 8 years old for Seth now

Seth is far years older than Anna, 8 = 4 years more than 4

Seth was 3 times older than Anna was then: 3(4-2)+2= 8
