Granpda and Grandma have 126 years togehter. How old is Grandma and how old is Grandpa, if Grandpa is twice older then Grandma was when Grandpa was as old as Grandma is now?

Most Common Suggestions I Make on the Forums.
1. Start by writing a balanced chemical equation.
2. Don't confuse thermodynamic stability with chemical reactivity.
3.

All it is is a simple system of equations.

<- A nice calculator for this.
I would put the answers, but I'll save Borek the work of erasing it.

Solving a system of 2 equations 2 unknowns isn't the difficult part, but rather establishing the equations, If you understand the question, it becomes very easy .

Good point. If you just find 1 <.> of 126 then you can figure it out from there.

You can even solve it by trial and error.
