let t = number of years in question
In 't' years, his mother will be 26+t and Xavier will be 2+t years old, then tack on *3 to match the problem statement:
26+t = (2+t)*3
26+t = 6+3t
-2t = -20
t = 10

Answer: in 10 years, Xavier's mother will be 3 times his age.

Check: 26+10 = 36
(2+10)*3 = 12*3 = 36 (ok)
