algerbra problem

there are 4 people in sams family the sum of their ages is 73 sam's father is 3 years older than his mother. sams sister is 2 years younger than him. but 4 year ago the sum of the ages of everyone in sam's family was 58.

how old is each of them now 

sams dad is 34

sams mum is 31

sam is 5 

sams sister is 3 

34 + 31 + 5 + 3=73

but 4 years ago there age amounted to 58 

sam dad is 30

sams mum is 27

sam is 1

so the answer is 30 + 27 + 1 = 58
