T= Tina's age
t+2= second child
t+4= third child
36= age of all children
Add the ages of all children equal to 36 years. Add 2 to each age because there is 2 years age difference between each child.
t + (t+2) + (t+4)= 36
combine like terms
3t + 6= 36
subtract 6 from both sides
3t= 30
divide both sides by 3
t= 10 Tina's age
t+2= 12
(10)+2= 12 age of second child
t+4= 14
(10)+4= 14 age of third child
ANSWER: The formula that will calculate Tina's age is t + (t+2) + (t+4)= 36.
