please answer this for me

Answer 1

Answer:

Jia Jia = 6 years

Kai Kai = 7 years

Explanation:

J + K = 9

K = J + 1

J = 2012 Jia Jia age

K = 2012 Kai Kai age

Replacing the second equation on the first equation:

J + (J+1) = 9

2J + 1 = 9

2J = 9 - 1

2J = 8

J = 8/2

J = 4 years

K = J+1

K = 4 + 1

K = 5 years

then:

2014 - 2012 = 2

J = 4 + 2 = 6 years

K = 5 + 2 = 7 years
