Answer 1

Answer:

A-48 B-12

Step-by-step explanation:

A=4B

A-10 = 19(B-10)

4B-10 = 19B - 190

solve it

Answer 2

Let age of a is x

and age of b is y

so according to data

x=4(y) ___1

also 10 year ago

(x-10)=19(y-10) ___2

by 2

=x-10 = 19y-190

=x-19y-180___3

by 1

x=3y___4

now use any method like elimination or substitution or cross multiplication and you will get x and then find y
