There are two statements about the ages. That means there are TWO equations. Let S be Sarah's age and T be Tom's age. Then: S = 6 + 3T .... "Sarah is 6 years older than 3 times the age of her son Tom" S  T = 28 .... "The difference in Sarahs age and toms age is 28 years" Since you know from common sense that Sarah is older than Tom, you can drop the absolute value bars and have two equations in two unknows. The second is now: S  T = 28 .... which you can rewrite as: S = T + 28 .... and use this to subsitute for S in the first equation: (T + 28) = 6 + 3T T + 22 = 3T .... subtracted 6 from both sides 22 = 2T .... subtracted T from both sides T = 11 .... divide both sides by 2, and put the variable on the left Tom is 11 years old. Sarah's age is 6+3T = 6 + 3(11) = 6 + 33 = 39 years.
