5 yrs ago Montys age was 5 years less than twice Rachels age. In 3 years, one third of Rachels age will be 12 years less than Montys age. How old are they now?

M5=2R+5
1/3(R+3)=(M+3)+12
Can you take it from here? 
No  that comes out to a negative number  doesnt it? Can you show the next steps?? I am not sure why it is not coming out
