John is two years older than are, who is twice as old is Lola, if the total of the age of John and ade and Lola is 27. How old is ade About the author Katherine
Answer: hey here is your solution pls mark it as brainliest so here we go Step-by-step explanation: so let age of John be x years,ade be y years and lola be z years so according to first criterion x=y+2 (1) according to second criterion y=2z (2) substitute value of y in (1) we get x=2z+2 (3) now according to third condition x+y+z=27 substitute values of x and y from (2) and (3) we get 2z++2z+z=27 ie 5z=25 ie z=5 years so substitute value of z in (2) ie y=2z ie y=2×5 ie y=10 years hence ade is 10 years old u can verify the answers by substituting values of x y and z in formed equations u can bet on my answer Reply
Answer:
hey here is your solution
pls mark it as brainliest
so here we go
Step-by-step explanation:
so let age of John be x years,ade be y years and lola be z years
so according to first criterion
x=y+2 (1)
according to second criterion
y=2z (2)
substitute value of y in (1) we get
x=2z+2 (3)
now according to third condition
x+y+z=27
substitute values of x and y from (2) and (3)
we get
2z++2z+z=27
ie 5z=25
ie z=5 years
so substitute value of z in (2)
ie y=2z
ie y=2×5
ie y=10 years
hence ade is 10 years old
u can verify the answers by substituting values of x y and z in formed equations
u can bet on my answer
