A is 20 year older than B. He is Also six times as old as B. Find their present ages? About the author Mary
A = 20 + B –(1) A = 6B substitute A = 6B in (1) 6B – B = 20 5B = 20 therefore B = 4 Substitute B = 4 in (1) A= 20 + 4 THEREFORE A = 24 , B = 4 Reply
Step-by-step explanation: A is 20 years older than B. Hence,A is x + 20 years old . A is also six time as old as B. Hence,age of A is 24 years and age of B is 4 years . Reply
A = 20 + B –(1)
A = 6B
substitute A = 6B in (1)
6B – B = 20
5B = 20
therefore B = 4
Substitute B = 4 in (1)
A= 20 + 4
THEREFORE A = 24 , B = 4
Step-by-step explanation:
A is 20 years older than B. Hence,A is x + 20 years old . A is also six time as old as B. Hence,age of A is 24 years and age of B is 4 years .
