Answer:
Sam is 19 years old.
Explanation:
If their ages add up to 27 and Sam was 19 then Susan would be 8 years old. 8+19=27.
19
Let Sam be x
Let Susan be y
x = y+11
x + y = 27
Substitute (x) with (y+11)
(y+11) + y = 27
Solve the equation
2y + 11 = 27
2y = 16
y = 8
Susan's age is 8.
Sam's age is 8 + 11
Sam's age is 19
Hope this helped :)
