Question

write and solve this equation: Samantha is one year less than twice her brother Jack’s age. If the sum of their ages is 41, how old is Samantha?

Answer 1

Answer:

Samantha's age = 27 years

Step-by-step explanation:

• Let Jack's age be = x

As Samantha is one year less than twice her brother Jack’s age.

• So Samantha's age = 2x-1

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
