Question 1189738
let Mr. Micklow's age be x years
 and Mrs. Craft's age be y years

The sum of Mr. Micklow and Mrs. Craft's age is 55.

So x+y =55
 The difference of their age is 3. What are their ages?
x-y =3
Add the two equations
we get 2x = 58
x= 58/2
x=29
substitute x 
in x+y =54
29+y =55
y= 26
Mr. Micklow's age  29 years
 and Mrs. Craft's age  26 years
