Answer:
Samantha's age = 27 years
Step-by-step explanation:
As Samantha is one year less than twice her brother Jack’s age.
As the sum of their ages is 41.
Thus, the equation become
x+2x-1 = 41
3x-1 = 41
3x = 42
Dividing both sides by 3
x = 14
It indicates that Jack's age = 14 years
Therefore,
Samantha's age = 2x-1 = 2(14)-1 = 27 years
