Robyn adopted a child who is exactly 28 years younger than her.
In one year's time, Robyn will be 3 times as old as her child will be.
How old is Robyn now?
If Robyn’s age is r then her child is r-28. In one year Robyn will be r+1 and her child r-27 r + 1 = 3(r - 27) r + 1 = 3r - 81 r - r + 1 + 81 = 3r - r - 81 + 81 82 = 2r r = 41 Robyn is 41 years old
