The age of a tortoise is 52 years more than the combined age of two elephants. In 10 years, the tortoise will be twice as old as the two elephants combined. How old is the tortoise now?

Hello Guest

 

\(t-e=52\\ t=52+e\\ t+10=2(e+10)\\ 52+e+10=2e+20\\ \color{blue}e=42\)

\(t=52+42\\ \color{blue}t=94\)

The tortois is now 94 years old.
