Question

yanira is 3 years older than tim and twice as old as hannah. tim is 2 years older than hannah. how old are yanira, tim, and hannah

Answer 1

Yanira = Y

Tim = T

Hannah = H

-----------------

Therefore:

Y=T+3

Y=2H

T=H+2

---------------

Now, we know that:

Y=T+3

But we also know that:

T=H+2

Therefore:

Y=(H+2)+3

Y=H+5

-------------------

Now we can combine the equations:

Y=H+5 

Y=2H

Therefore:

2H=H+5

2H-H=5

So, H=5.

---------------------

If H=5,

Y=2H=2*5=10

---------------------

If H=5,

T=H+2=5+2=7

-----------------------

Answers:

Yanira is 10 years old.

Tim is 7 years old.

Hannah is 5 years old.
