brian is 26 years older than his daughter kim. the sum of their ages is twice the differences of their ages. find their ages.

algebra 
Reiny,
age of daughter  x
brian's age  x+26
now just translate ....
"the sum of their ages is twice the differences of their ages"
x + x+26 = 2(x+26  x)
continue ....
