Ray is 23 years older than his sister carol. in 20 years he will be twice as old as carol. how old is each of them now?

 r = c+23 

r+20 = 2(c+20) 
(c+23)+20 = 2(c+20) 
c+43 = 2c+40 
c = 3 : r = c+23 = 26

Carol is 3 years of age, and Ray is 26 years of age.

Ray is going to be 86 and Carol is 43.
23+20=43 x 2=86 
86/2=43
