A man is twice as old as his son. When his son is the same age as his father was when he was twice as old as his son, both of their ages add to 180 years old. What are the ages of the man and his son through both of these time periods?
My attempt: $$m_1=2s_1=s_2$$ $$m_2+s_2=180$$
I really can't go farther than this, as I don't know what to do.
