Question

Samuel and Jackson are brothers. Samuel is three years older than twice the age of Jackson. If the sum of their ages is 18, how old are the brothers?

Answer 1

Answer:

Samuel = 13yrs

Jackson = 5yrs

Step-by-step explanation:

Samuel = 2x + 3

Jackson = x

sum = 18

2x + 3 + x = 18

3x = 18 - 3

3x = 15

x= 5yrs

Samuel = 2x + 3

             = 10 + 3

             = 13 yrs

Jackson = x

             = 5yrs
