Math problem?

lily is 16 years younger then danny. danny is two more then twice lily%26#039;s age.


what are there ages?





please explain how to do this :]

Math problem?
Use algebra.





Let x = lily%26#039;s age, and x + 16 = danny%26#039;s age.





Danny is two more than twice lily%26#039;s age:


x + 16 = 2x + 2





Then solve the equation you get:


x + 16 = 2x + 2


16 = x + 2


x = 14


x + 16 = 30





Lily is 14, Danny is 30.





Hope that helps!
Reply:Let





X = Lily%26#039;s age


Y = Danny%26#039;s age





Since Lily is 16 years younger than Danny, then





Y = X + 16 (Equation 1)





and since Danny is 2 more than twice Lily%26#039;s age





Y = 2X + 2 (Equation 2)





Since Equation 1 is equal to Equation 2,





X + 16 = 2X + 2





2X - X = 16 - 2


X = 14





Solving for Y (from Equation 1),





Y = X + 16 = 14 + 16 = 30





Danny is 30 years old and Lily is 14 years old.
Reply:replace lily with x and danny with y.


x+16=y y+2=2x therefore y=2x-2


that means x+16=2x-2


x+16-2=2x


x=14 y=16+14=30


lily is 14 yrs old danny is 30 yrs old
Reply:let lilly%26#039;s age be x


danny%26#039;s age be y


y-16=x


y=2x+2





solving these 2 equations





x=14(lily%26#039;s age)


y=30(danny%26#039;s age)
