Question

Harvey is 3 times as old as Jane. The sum of their ages is 48 years.
Find the ages of Harvey and Jane.

Answer 1

H = 3j
H + J = 48

we know what H equals so sub it into the second equation

3J + J = 48
4J = 48
J = 12

so If Jane is 12

Check to see if H = 3j
H = 3(12)
H = 36

does 36 + 12 = 48? yes

and is 36, 3 times more than 12? yes it is

Answer 2

yes it is
