Cate's mother is four times as old as Cate is now. In 6 years, Cate's mother will be three times as old a Cate will be then. How old is Cate now (IN YEARS)?

c = cate now

 

m = 4 c  

 

in 6 yrs :    m+ 6 = 3 * ( c+6)      sub in red equation

                 4c  + 6 = 3 ( c+6)      solve for c
