William is 3 times elder than monica. in 6 years william will be twice as old as monica. what are their current ages. use an equation to solve.

William's age is 18 years old and Monica's age is 6 years old

Step-by-step explanation:

Let

x > William's age

y > Monica's age

we know that

x=3y > equation A

(x+6)=2(y+6) > equation B

Substitute equation A in equation B and solve for y

(3y+6)=2(y+6)

3y+6=2y+12

3y-2y=12-6

y=6 years

Find the value of x

x=3(6)=18 years

therefore

William's age is 18 years old

Monica's age is 6 years old

answer: 12
